A temperature control device includes a temperature detector, a difference operation unit, a controller, a saturation processing circuit unit, a rewritable storage unit, and a conversion unit. The difference operation unit operates a digital value corresponding to a difference value between a detected temperature value and a target temperature. The controller calculates a manipulated variable using the digital value operated by the difference operation unit. The saturation processing circuit unit includes a digital circuit to limit an output value of the controller to a pre-set upper limit value. The rewritable storage unit stores the upper limit value read from a storage area of the rewritable storage unit and input into the saturation processing circuit unit. The conversion unit converts the output value of the saturation processing circuit unit into an analog signal to output the converted value as a control command value to the heater.

A microphone can include at least two deformable elements anchored at a center and sharing a common backside cavity. The at least two deformable elements can be deformable under pressure. Vibration modes of the at least two deformable elements can be coupled such that a first vibration mode can be associated with a uniform movement of all deformable elements and a second vibration mode can be associated with out-of-phase movements among the deformable elements. Deformation of each deformable element can be detected via a sensing material in contact with each deformable element to form a sensing port. Thus, the microphone can include at least two sensing ports and signals from the at least two sensing ports can be subtracted using analog or digital electronics to yield a signal responsive primarily to a pressure gradient along an axis.

This invention discloses a device, system, and method for precise time measurement of PET using lasers. The device for precise time measurement of PET using lasers includes a PET detector module, a PET digital electronics board, and a laser. The PET detector module detects gamma photons emitted by the target and sends the generated detection signal to the PET digital electronics board. The PET digital electronics board is equipped with an optoelectronic device for receiving light pulse signals and converting them into a clock reference signal. The laser generates light pulse signals and sends them to the optoelectronic device. The PET digital electronics board digitizes the received detection signal according to the clock reference signal and measures the time. This device improves upon traditional PET systems, fully leveraging the time performance advantages of the detector, electronics, and other components.

Analog optical neural networks (ONNs) can reduce the energy of matrix-vector multiplication in neural network inference below that of digital electronics. However, realizing this promise remains challenging due to digital-to-analog (DAC) conversion—even at low bit precisions b, encoding 2b levels of digital weights and inputs into the analog domain involves power-hungry electronics. Faced with similar challenges, telecommunications uses complex-valued Quadrature-Amplitude Modulation (QAM). QAM maximally exploits the complex amplitude to provide a quadratic 0(N2)→0(N) energy saving over intensity-only modulation. QAMNet, an ONN with lower energy consumption than existing ONNs, uses the complex nature of the amplitude of light with QAM. QAMNet accelerates complex-valued deep neural networks with accuracies indistinguishable from digital hardware. Compared to standard ONNs, QAMNet ONNs are (1) more accurate above moderate levels of total bit precision, (2) more accurate above low energy budgets, and (3) an optimal choice when hardware bit precision is limited.
