  • Patent number: 10433414
    Abstract: A method of manufacturing a printed circuit board includes providing a substrate having at least one resin plate and a semi-cured sheet. A through hole is formed in the substrate to accommodate a radiator having an electrically conductive layer and an electrically insulated layer. The substrate and radiator are heat pressed to fully cure the epoxy and couple the substrate and radiator together. The excess resin is removed and electrically conductive layers are plated on the board. Surface circuits and a heat dissipating pattern are then etched into the conductive layer. An LED is attached to the printed circuit board. In some embodiments, a flexible segment is formed by removing a portion of the substrate. The radiator can have an electrically insulated layer extending at least partially across a surface of an electrically insulated and thermally conductive core.

  • Patent number: 10322436
    Abstract: A method of applying a riblet structure coating on the internal surface of a pipe includes coating the internal surface of a pipe with a resin layer and applying a cavity mold having a reverse riblet pattern structure to the coated internal surface of the pipe. A flexible air bag is inserted into the interior of the pipe and charged with air to hold the mold against the coated internal surface of the pipe. The air bag may be charged with air for a sufficient amount of time to allow the coating to cure in the riblet shape of the mold. Afterwards, the air bag and the mold are removed from the pipe to yield a pipe coated with an internal riblet structure.

  • Patent number: 10291065
    Abstract: A smart plug that is partitioned into a plurality of printed circuit boards (PCBs) in a three dimensional manner to reduce its size. Aspects consider the effect of the possible increased internal temperature as the size of the smart plug is reduced. For example, thick metal foils connect various components of a smart plug to reduce heat dissipation within the smart plug. Also, a metal foil may transfer heat from contact metal on a PCB to a side wall of a plastic housing of the smart plug. The smart plug may comprise a computing device that obtains information identifying the attached electrical device and accesses device data about the time duration during which the attached electrical device exhibits transient characteristics. The computing device then uses the accessed data to effectively control the attached electrical device.

  • Patent number: 10127925
    Abstract: A system and method for processing a plurality of channels, for example audio channels, in parallel is provided. For example, a plurality of telephony channels are processed in order to detect and respond to call progress tones. The channels may be processed according to a common transform algorithm. Advantageously, a massively parallel architecture is employed, in which operations on many channels are synchronized, to achieve a high efficiency parallel processing environment. The parallel processor may be situated on a data bus, separate from a main general purpose processor, or integrated with the processor in a common board or integrated device. All, or a portion of a speech processing algorithm may also be performed in a massively parallel manner.

  • Publication number: 20170164324
    Abstract: Disclosed are methods and apparatus optimizing the performance of a radio access technology, such as LTE, in a single radio wireless communication system supporting multiple radio access technologies, such as both LTE and 1x CDMA. The methods and apparatus effectuate this optimization in a single radio LTE (SRLTE) device, for example, through increasing system parameters, such as Slot Cycle Index (SCI) related to a maximum allowed periodicity of when a wireless device tune away from a LTE data call to monitor paging from 1x CDMA. Increasing the SCI value in the wireless device reduces the periodicity of 1x CDMA paging tune away from an LTE data call, thereby optimizing the LTE performance.

  • Patent number: 9538421
    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first device. The first device operates a ROHC compressor in a first state at a ROHC sublayer to compress a first packet to be transmitted to a second device. The first packet includes information for a ROHC decompressor to establish a ROHC context. The information enables the ROHC decompressor to decompress a second packet compressed by the ROHC compressor when operating in a second state. The first device determines, at a sublayer or a layer lower than the ROHC sublayer, whether the first packet has been successfully received at the second device. The first device continues operating the ROHC compressor in the first state in response to a determination that the first packet has not been successfully received at the second device.
