Abstract: A biosensor obtains at least a first photoplethysmography (PPG) signal at a first wavelength from a user and a second PPG signal obtained at a second wavelength from the user. The biosensor determines a first R value of the user using the first PPG signal and the second PPG signal and compares the first R value of the user to a normal range of R values for a blood type of the user. The biosensor determines a color of blood of the user using the first, second or another PPG signal and determines an abnormal condition that affects red blood cells of the user in response to the color of the blood and/or in response to the comparison or the first R value of the user to a normal range of R values for a blood type of the user.

Abstract: Video samples from a camera or cameras of a mobile device are sent as analog levels to a system-on-chip (SoC) or other processor of the device. The analog levels are the analog video samples or be an encoded form of the video samples. The samples are converted to digital and interpolated within the SoC to produce digital RGB samples suitable for display. Or, the analog video samples are interpolated within the SoC using analog processing to produce analog RGB samples. Or, only the G samples are transmitted to the SoC, and processed using analog processing. After processing within the SoC, the samples are sent as analog levels or in encoded form to a corresponding receiver of a display integrated with column drivers. Digital functionality of the DDIC of the display is moved into the SoC or into circuitry separate from, and connected to, the SoC via an MIPI DSI interface.

Abstract: There is provided a pipette for aspirating and/or dispensing liquids, comprising a pipette tip and a plunger. The pipette tip has a proximal end and a distal end defining a longitudinal axis therebetween; an aperture at the distal end, and a fluid cavity extending from the aperture at least partially towards the proximal end. The plunger is positioned inside the pipette tip, and extends at least partly between the proximal and distal ends of the pipette tip into the end portion, and is movable towards and away from the aperture to aspirate or dispense fluid from the pipette tip. The pipette tip has an end portion disposed at the distal end, having an inner wall surface extending at an angle of between 2 degrees and 5 degrees relative to the longitudinal axis, for at least 5 mm.

Abstract: A heating, ventilation, and air conditioning (HVAC) unit including a variable-speed drive and a bypass circuit is provided. Under normal operation, the drive receives line voltages as inputs and provides variable-speed control signals to components of the HVAC unit (for example, a compressor, fan motor, etc.). The drive allows the HVAC to operate at below maximum capacity, which increases the efficiency of the HVAC unit. When a fault condition is detected in the drive, the HVAC unit automatically switches to the bypass circuit such that the line voltages are provided directly to the components. This results in the HVAC unit operating at maximum capacity for a period of time, but allows the HVAC unit to continue operation even when the drive is experiencing the fault condition.

The plunger is positioned inside the pipette tip, configured to extend between the proximal and distal ends of the pipette tip, and movable toward and away from the aperture. The system is configured to carry out at least two different operating methods for dispensing liquid.
