Wasn’t we on 80c a month before the last quarter and then went to $1.20 just after release. Have a feeling everyone that brought on hoping for better news is now selling again. Maybe I’ll hold out to low 90s and possibly 80s, especially as it don’t look like the company is ever going to assist the sp.
Morning Rocket577,
Aaaah, the tranquillity of the Great Southern Ocean.

I think BRN management has adopted the practice of concentrating on the business and the share price will eventually take care of itself. An ex-market-darling Livetiles is delisting itself on the ASX saying that the continued weakness of share price may distract management on its business. That is basically saying management has no control of the share price, long or short term.
The buyers are expecting the share price to go up and sellers and shorters believe the share price will go down.
At the end of the day, it is the investors who decide what the fair value of a company is at any point in time, not bankers, analysts or brokers.

Reducing power consumption in battery-powered devices
Many devices in IoT-based systems are designed with a small form factor and are battery powered. Battery replacement in a commercial infrastructure usually involves the dismantling and refitting of electronic components, including the sensors that form the backbone of Internet of Things (IoT) technology. Such efforts consume a substantial amount of time and manpower, as a commercial building network may contain thousands of these devices. This makes energy-efficient, battery-powered, portable sensors and actuators the most acceptable solution for retrofitting operations. Increasing the battery life of these sensors improves system reliability by reducing the downtime caused by a single node running out of battery. This article discusses the energy consumption challenges that IoT devices face and possible solutions, including the use of ultra-low power sensors.
Energy usage in wireless sensors
With the rise of IoT, embedded designers are more than ever focusing their attention and efforts on system energy usage. One example of a purpose-built product in this regard is a battery-powered wireless sensor node. The operation of a wireless sensor comprises a series of events, with each event requiring a certain amount of power. These events include:
These activities are responsible for high battery power consumption and discharge. Figure 1 illustrates current consumption in a battery-powered wireless sensor during its three main states: active, idle, and sleep.
- Waking up, measuring the relevant parameters, and processing the data into messages
- Powering up the radio frequency amplifier, transmitting the messages, and powering down the radio frequency power amplifier
Figure 1: Power consumption in battery-powered sensors during their three main states
Source: eenewsanalog.com
There are multiple techniques and design strategies designed to decrease power consumption and optimize power-saving performance: hardware or software energy optimization, network optimization, and energy harvesting.
Hardware Optimization
Design engineers can choose microcontroller units (MCUs) that are designed specifically for low-energy consumption. An MCU, however, isn’t the only potential energy hog in an IoT device. Opting for low-power sensors and nodes can also substantially reduce power consumption.
Network Optimization
Choosing a connectivity solution for any IoT device depends heavily on the application’s chosen components, the performance of the connected objects, and their energy consumption. IoT applications with low power requirements can make use of Low Power Wide Area Network (LPWAN) for long-distance connectivity, while battery-powered IoT devices can use Bluetooth Low Energy (BLE) for short to-medium communication ranges. The distance between two nodes, system topology, data rate, and the message size are all factors that influence the transmission time, which in turn impacts power consumption.
Optimizing software for low power consumption
Programming the device to run in low power modes, rather than active modes, will make a significant difference in conserving battery power. New developments in low power management have introduced a wide range of ultra-low-power sleep modes. Whereas previous devices have only differentiated between run and idle modes, current devices feature more levels of granularity, including standby, doze, sleep, and deep sleep. Applications are programmed to spend as little time as possible in the MCU’s active mode. This might mean simplifying calculations, batching operations, or transitioning to an asynchronous and interrupt-driven design.
Applications
Weather Station Solution
Figure 2: IoT-based Indoor Air Quality measurement
Source: Renesas
This weather station solution supports smart home and agriculture systems where an indoor controller unit aggregates weather data (temperature, humidity, and CO2concentration). The weather data is measured by an outdoor unit that is solar powered and features an ultra-low-power MCU. The indoor and outdoor units are connected via BLE, and captured data is communicated to the Cloud via Wi-Fi. Renesas’ ZMOD Digital Gas Sensor family uses embedded artificial intelligence (AI) technology and leverages different Operating Modes, which use time, temperature, and gas signatures that enable unique signals from a highly trained machine learning (ML) system. The outdoor unit is controlled by an ultra-low power RE01 MCU. The indoor unit is controlled by an RX-based 32-bit MCU with added security features that make it suitable for cloud communication.
IoT Cold Chain Monitoring
Figure 3: IoT-based Cold Chain Monitoring
Many industries, including agriculture, pharmaceuticals, and logistics require refrigerated storage for their products and ingredients. An IoT-based cold chain monitoring solution allows temperature and humidity to be measured from a remote location, with alerts set up for temperature changes and anomalies, preventing waste and spoilage as ingredients move through the supply chain. The system is controlled by a Renesas RA4W1 32-bit MCU, using Bluetooth LE 5.0 for wireless communications. Sensors include the ZMOD4410 indoor air quality sensor and the HS3001 temperature and humidity sensor.

The ZMOD4510 Outdoor Air Quality (OAQ) Platform is a gas sensor system that can be used in a variety of indoor and outdoor applications. The ZMOD4510 uses machine learning and traditional methods to determine Air Quality Index (AQI), which is based on concentrations of gases in the atmosphere, including nitrogen dioxide (NO). The ZMOD4510 currently has two released operation modes.
Table 1: Air Quality Index Levels Described by the EPA
Air Quality Index (AQI) Level of Concern and Air Quality Condition O3Concentration 1h average [ppb][a] O3Concentration 8h average [ppb] NO2Concentration 1h average [ppb] Color Code 0 to 50 Good 0 to 62 0 to 54 0 to 53 Green 51 to 100 Moderate 63 to 124 55 to 70 54 to 100 Yellow 101 to 150 Unhealthy for Sensitive Groups 125 to 164 71 to 85 101 to 360 Orange 151 to 200 Unhealthy 165 to 204 86 to 105 361 to 649 Red 201 to 300 Very Unhealthy 205 to 404 106 to 200 650 to 1249 Purple 301 to 500 Hazardous 405 to 604 - 1250 to 2049 Maroon
Operation Mode 1 allows a general measurement of Air Quality (AQ), including the non-selective measurement of NO2 and O3. The AQI is determined based on the classifications by the EPA (Environmental Protection Agency) for O3 and NO2 levels (Table 1).
Operation Mode 2 allows the selective measurement of O3 with a fast sample rate of two seconds. With an average consumption of 0.2mW, power consumption is minimal. The second-generation OAQ algorithm is specifically designed to detect ozone, and the cross-sensitivity response to NO2 is reported as less than 25 AQI, even at NO2 levels up to 200ppb.

Renesas’ HS3001 sensor is a MEMS-based relative humidity and temperature sensor. It features fast measurement response time (typically 6 seconds) with high accuracy. The HS300x is factory-programmed to operate in Sleep Mode. In Sleep Mode, the sensor waits for commands from the controller before taking any measurements. The digital core only performs conversions when it receives a measurement request command (MR); otherwise, it remains powered down. It consumes a minimal amount of power: an average of 1.0µA with one RH+T measurement per second, 8-bit resolution, and a 1.8V supply. Its low power consumption, along with its small form factor (3.0 x 2.4 x 0.8 mm), make it well suited for use in portable, battery-operated devices.

Summing up: Low power sensors for IoT
Power consumption plays an important role in IoT devices and nearly all embedded devices. Choosing components capable of running at reduced power, including MCUs, power sources, communication protocols, and sensors, diminishes power consumption concerns. Sensors are the primary element of any IoT-based system and should ideally consume minimal power without compromising their static and dynamic characteristics. Renesas offers a variety of sensors that are designed for use in IoT systems and feature low power operation modes that greatly extend the life of battery-powered devices.
No. Phrases like "low power", "embeded AI" just don't cut it.
When Renesas puts Akida IP into a sensor, they, and BRN will tell us. When Renesas makes the arm M33+Akida IP chip available to OEMs they will tell us - just ask Tony Dawe. (Hi Tony!)

perhaps an indirect connection would be more accurate.
Partnerbase
Microchip Technology and Edge Impulse have an active Technology Partner. Together they have 145 partners and share 0 partners.www.partnerbase.com
So Edge Impulse have a connection with Microchip...
Just being a smart arse.. i like speculation and all that. But prefer legitimate evidence there is a link between brn and microchip.

Further to previous post above on the Intellisense solicitation / proposal with NASA I can see they have just been awarded the contract PO.
Again, this one did not specifically mention Akida though we know they have done in the past and that we work with them and trust our tech will get a test at least in the dev.
It does specify the following from the proposal:
Technical Abstract (Limit 2000 characters, approximately 200 words):
NASA is seeking innovative neuromorphic processing methods and tools to enable autonomous space operations on platforms constrained by size, weight, and power (SWaP). To address this need, Intellisense Systems, Inc. (Intellisense) proposes to develop an Adaptive Deep Onboard Reinforcement Bidirectional Learning (ADORBL) processor based on neuromorphic processing and its efficient implementation on neuromorphic computing hardware. Neuromorphic processors are a key enabler to the cognitive radio and image processing system architecture, which play a larger role in mitigating complexity and reducing autonomous operations costs as communications and control become complex. ADORBL is a low-SWaP neuromorphic processing solution consisting of multispectral and/or synthetic aperture radar (SAR) data acquisition and an onboard computer running the neural network algorithms. The implementation of artificial intelligence and machine learning enables ADORBL to choose processing configurations and adjust for impairments and failures. Due to its speed, energy efficiency, and higher performance for processing, ADORBL processes raw images, finds potential targets and thus allows for autonomous missions and can easily integrate into SWaP-constrained platforms in spacecraft and robotics to support NASA missions to establish a lunar presence, to visit asteroids, and to extend human reach to Mars. In Phase I, we will develop the CONOPS and key algorithms, integrate a Phase I ADORBL processing prototype to demonstrate its feasibility, and develop a Phase II plan with a path forward. In Phase II, ADORBL will be further matured, implemented on available commercial neuromorphic computing chips, and then integrated into a Phase II working prototype along with documentation and tools necessary for NASA to use the product and modify and use the software. The Phase II prototype will be tested and delivered to NASA to demonstrate for applications to CubeSat, SmallSat, and rover flights.

As I understand, Shorters are traders who are allocated shares by a company that has shares in BRN . The trader does not pay immediately for those shares . The trader sells them immediately in the hope that the share price will fall at which time he buys the shares back with the money he received from selling them at the higher price hopefully buying back enough to return to the lending company and some left over free for the traders risk

Yep, I get the shorting part, but I was more questioning your thoughts on why more shorting today? And what the Bank of America reference had to do with it? Cheers.

I dare say he is referring to this:
Investors aren't 'apocalyptically' bearish anymore
Investors are betting inflation has peaked and interest rate shocks are about to come to an end, a Bank of America survey shows. Read more
“Sentiment remains bearish, but no longer apocalyptically bearish as hopes rise that inflation and rates shocks end in coming quarters,” Hartnett said.

Think investors want more when it comes to announcements now with BRN, I know I do.
It would have taken a lot of work to pull all those uni's in, even if we did have to give away 30 akida boards. So well done Sean!
It's a great sign of acceptance of our IP. I love the press release. (But I also like the escaping donkeys.)
