Patent number: 11911128Abstract: A mote includes an optical receiver that wirelessly receives a power and data signal in form of NIR light energy within a patient and converts the NIR light energy to an electrical signal having a supply voltage. A control module supplies the supply voltage to power devices of the mote. A clock generation circuit locks onto a target clock frequency based on the power and data signal and generates clock signals. A data recovery circuit sets parameters of one of the devices based on the power and data signal and a first clock signal. An amplifier amplifies a neuron signal detected via an electrode inserted in tissue of the patient. A chip identifier module, based on a second clock signal, generates a recorded data signal based on a mote chip identifier and the neuron signal. A driver transmits the recorded data signal via a LED or a RF transmitter.Type: GrantFiled: February 11, 2021Date of Patent: February 27, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: David T.

Patent number: 7895466Abstract: An integrated circuit includes a DMA controller for performing conventional DMA transfers and for backing-up and restoring data during low power events. The integrated circuit includes one or more processor components, one or more peripheral components, a power management circuit and the DMA controller. The power management circuit manages power control within the integrated circuit. The DMA controller includes a DMA engine for executing DMA transfers between different ones of the components and memory based on configuration parameters provided to the DMA engine. A detection circuit configured determines if the power management circuit initiates a power state change. The DMA controller also has circuitry for providing a first set of configuration parameters to the DMA engine if no change in power state is detected and overriding the first set of configuration parameters with a second set of configuration parameters if a change in power state is detected.Type: GrantFiled: September 2, 2008Date of Patent: February 22, 2011Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventor: David Barrow

Publication number: 20070168579Abstract: PPP frame encapsulation of IP frames—including FCS calculation, character escaping, and HDLC flag insertion—is performed by hardware acceleration circuits within a DMA module as part of a DMA transfer autonomously of a processor. Software may preprocess the IP packets prior to the hardware-accelerated processing. The hardware acceleration in the DMA module may additionally decapsulate PPP frames—including FCS calculation and comparison for error detection, escaped character recovery, and frame boundary detection—to assist in the formation of IP packets. The hardware-accelerated PPP framing may be particularly useful when a mobile terminal provides internet access, through a wireless communication network over packet data channels, to an attached peripheral device, such as a computer.Type: ApplicationFiled: September 20, 2005Publication date: July 19, 2007Inventors: William Croughwell, David Barrow
