  • Publication number: 20200041990
    Abstract: Operational facets of a compressor are controlled from a remotely-located computer. Data from the compressor is automatically collected at a first data store every first time increment of a first time period. Portions of the data from the first data store are automatically collected at a second data store every second time increment of each first time period. The second time increment is greater than the first time increment, and the portions of the data are collected for a second time period which is greater than the first time period. Successful verification of user authentication data collected at the computer causes automatic generation of an image of application icons at the computer to enable the computer as an input device for controlling the compressor and selections of routines available at an analytics visualization generator that uses data from the second data store.

  • Publication number: 20200042030
    Abstract: Existing proportional to absolute temperature (PTAT)/complementary-to-absolute-temperature (CTAT) reference voltage circuit requires a large components count and foot print, precise device matching for accuracy and unsatisfactory sensitivity error or variation to temperature and humidity. The present invention relates to a novel approach for such reference voltage circuit based on a self-biased complementary pair of n-type and p-type current field-effect transistors, which provides rail PTAT, rail CTAT and analog reference voltages.

  • Publication number: 20200042032
    Abstract: A system for a network of one or more off-board subsystems is provided for controlling automobile subsystems such as vehicle lighting. Such a system may be compatible with a universal asynchronous receiver transmitter (UART) interface and it may address timing issues by using a protocol having a synchronization frame (sync frame) such that a clock signal may be recovered from the sync frame sent by an off-board master device 202, such as a microcontroller unit 208, to a satellite/slave 211 device. Such a protocol permits elimination of a crystal clock oscillator and phase-locked loop located at satellite, thereby dispensing with an otherwise significant cost.

    Abstract: An integrated circuits with sequential logic circuitry is provided. The sequential logic circuitry may including latching circuits that receive clock signals from on-chip or off-chip clock sources. The clock signals may exhibit clock skew that is native to the integrated circuit. The natively existing clock skew can be leverage to perform time borrowing to help optimize circuit performance. The desired clock skew can be achieved by intelligent placement of the clock sources and deliberate routing of the clock signals from the clock sources to respective types of clock distribution networks on the integrated circuit.

  • Publication number: 20200042034
    Abstract: The disclosed embodiments relate to a technique that uses a modified timing signal to reduce self-induced voltage noise in a synchronous system. During a transient period associated with a deterministic event in the synchronous system, the technique uses a modified timing signal generated based on a normal timing signal as a timing signal for the synchronous system. Outside of the transient period, the technique uses the normal timing as the timing signal for the synchronous system. In some embodiments, the modified timing signal is generated by skipping a pattern of clock transitions in the normal timing signal.
