Abstract: A method for reducing probability of ice nucleation during preservation of biological matter in isochoric systems by placing biological matter in a flexible, impermeable inner container, adding an inner solution with a melting point that is higher than a desired storage temperature, removing bulk gas from and sealing the inner container, placing the inner container in a rigid, non-thermally insulating outer container, filling the space between the inner and outer containers with an outer solution, removing bulk gas from and sealing the outer container, cooling the system to the desired storage temperature, maintaining the desired storage temperature for a desired storage period, warming the system to a temperature that is higher than the desired storage temperature, unsealing the outer and inner containers, and removing the biological matter. The outer solution has a melting point that is lower than the equilibrium melting point of the biological matter and the inner solution.

Abstract: Techniques are described for efficient high-resolution output of an image captured using a high-pixel-count image sensor based on pixel binning followed by luminance-guided umsampling. For example, an image sensor array is configured according to a red-green-blue-luminance (RGBL) CFA pattern, such that at least 50-percent of the imaging pixels of the array are luminance (L) pixels. Pixel binning is used during readout of the array to concurrently generate a downsampled RGB capture frame and a downsampled L capture frame. Following the readout, the L capture frame is upsampled (e.g., by upscaling and interpolation) to generate an L guide frame with 100-percent luminance density. An upsampled RGB frame can then be generated by interpolating the RGB capture frame based both on known neighboring RGB information (e.g., from the RGB capture frame and previously interpolated information), as adjusted based on local luminance information from the L guide frame.

Abstract: An image sensor includes ADCs, each including a comparator receiving a ramp signal and an image signal, and generating a comparator output. Each ADC also includes a counter ceasing to change a digital count value in response to a change in the comparator output. The digital count value has a first resolution. Each ADC also includes a delay line circuit including a delay line generating a first digital value encoding a duration of a period of the counter clock and generating a second digital value encoding a first portion of the period of the counter clock. Each ADC also includes a delay to digital circuit generating a digital output value based on the first and digital values. The digital output value encodes a second value of the ramp signal, where the digital count value has a second resolution that is greater than the first resolution.

Abstract: Techniques are described for disparity-preserving pixel binning during consistently binned parallel readout of an imaging sensor array having both phase detection autofocus (PDAF) pixels and imaging pixels. Each group of PDAF pixels and each group of imaging pixels is coupled with pixel actuators according to an particular arrangement, so that consistently applied control of the pixel actuators results in desired binning of both the PDAF pixels and the imaging pixels. According to some implementations, though such control of the pixel actuators is consistently applied across the pixels of the array, parallel readout of the sensor array yields diagonally binned imaging pixels, but vertically binned PDAF pixels to preserve horizontal PDAF disparity information. Additionally or alternatively, disparity-inducing structures are configured to position same-disparity PDAF pixels so that consistently applied control of the pixel actuators preserves disparity information during binning.

Abstract: Techniques are described for efficient staggered high-dynamic-range (HDR) output of an image captured using a high-pixel-count image sensor based on pixel binning followed by luminance-guided upsampling. For example, an image sensor array is configured according to a red-green-blue-luminance (RGBL) CFA pattern, such that at least 50-percent of the imaging pixels of the array are luminance (L) pixels. In each image capture time window, multiple (e.g., three) luminance-enhanced (LE) component images are generated. Each LE component image is generated by exposing the image sensor to incident illumination for a respective amount of time, using pixel binning during readout to generate appreciably downsampled color and luminance capture frames, generating an upsampled luminance guide frame from the luminance capture frame, and using the upsampled luminance guide frame to guide upsampling (e.g., and remosaicking) of the color capture frame.

Abstract: A method of pairing a therapeutic product delivery device to a handset is described. The handset is restricted to controlling only delivery devices which it is paired with. The method comprises the steps of: at the delivery device, setting, in response to the delivery device being connected to a charging device, a pairing indicator indicating that the delivery device is available for pairing, and broadcasting the pairing indicator using a radio transceiver; at the handset, discovering the delivery device based on the broadcast pairing indicator; and pairing the discovered delivery device and the handset together. By limiting the handset to pairing with devices which are broadcasting a pairing indicator, and by limiting the setting and/or broadcast of the pairing indicator to when the delivery device is connected to a charging device, the risk of accidentally pairing the wrong delivery device (for example someone else's) to the handset is greatly reduced.

Abstract: Techniques are described for implementing reduced-noise pixel ramp voltage generators for image sensors. The described pixel ramp voltage generators include circuit blocks to address various conventional causes of ramp generator noise. For example, a reference current is generated. Current steering can be used to toggle between a ramp-run mode for generation of a ramp voltage, and a ramp-stop mode for stopping the generation, thereby mitigating changes in low-frequency noise components between pixel conversion cycles, or phases or such cycles. Buffer multiplier techniques can be used to isolate kickback noise of the pixel conversion comparators from components generating the ramp voltage, such as to mitigate image smearing. Some implementations include additional features, such as sample-and-hold techniques used to isolate ramp generation components from current generation component noise, slope calibration techniques to dynamically tune voltage ramp slope, reset techniques, etc.
