  • Publication number: 20240093927
    Abstract: Disclosed herein are systems and methods for a method for controlling the temperature of a surface. In some embodiments, the method includes applying a variable input to a heat pump (e.g., a Peltier) in thermal communication with the surface. The variable input may vary about a voltage and may include a powered period and an unpowered period. In some embodiments, the method includes measuring a temperature of an element in thermal communication with the surface, determining, based on the temperature of the element, whether a temperature of the surface is within a safe temperature range for a user in thermal communication with the surface, in response to determining the surface is not within the safe temperature range, adjusting the voltage of the variable input to the heat pump, and in response to determining the surface is within the safe temperature range, continuing operation of the variable input at the voltage.

  • Publication number: 20240004952
    Abstract: A bit-widths determination method selects bit-widths for mixed-precision neural network computing on a target hardware platform. An activation quantization sensitivity (AQS) value is calculated for each convolution layer in a neural network. The AQS value indicates the sensitivity of convolution output to quantized convolution input. One or more convolution layers are grouped into a quantization group, which is to be executed by a corresponding set of target hardware. A group AQS value is calculated for each quantization group based on the AQS values of the convolution layers in the quantization group. Then bit-widths supported by the target hardware platform are selected for the corresponding quantization groups. The bit-widths are selected to optimize, under a given constraint, a sensitivity metric that is calculated based on each quantization group's group AQS value.

  • Patent number: 7598032
    Abstract: Modified thermostable DNA polymerases having enhanced efficiency for incorporating unconventional nucleotides such as those labeled with fluorescein family dyes are advantageous in many in vitro DNA synthesis applications. Such enzymes are particularly useful for use in chain termination nucleic acid sequencing protocols, as are native forms of such enzymes. Genes encoding the modified enzymes and methods for their production and use offer cost and efficiency advantages for DNA sequencing.
