  • Patent number: 11065457
    Abstract: A method for waking up an implantable medical device from a dormant state, an implantable medical device, and a system that includes such an implantable medical device and an external device. The implantable medical device is woken up from a dormant state by sending a modulated wakeup signal via a wireless link from an external device. The modulated wakeup signal is demodulated by way of a demodulator circuitry of the implantable medical device so as to produce a demodulated wakeup signal. The demodulator circuitry is permanently ready for operation. An awake state of the implantable medical device is then activated in response to the demodulated wakeup signal.

  • Patent number: 11057147
    Abstract: A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

  • Patent number: 11038622
    Abstract: Service modes specify how digital content is formatted in sidebands of an FM radio channel. In an improved service mode, encoded bits can be distributed between an in-band encoded component and a cross-band encoded component, where the encoded bits in the in-band encoded component are desynchronized by a specified duration with respect to the encoded bits in the cross-band encoded component. The encoded bits in the in-band encoded component can be allocated into frequency partitions that are used by a legacy service mode, such as MP1 or MP3, which can provide backward compatibility with the legacy service mode. The encoded bits in the cross-band encoded component can be allocated into frequency partitions that are not used by the legacy service mode, and are found in the opposite sideband, compared with the legacy service mode, which can provide time diversity within a single sideband.

  • Patent number: 10812790
    Abstract: The present technology relates to a data processing apparatus, data processing method, and a program which improve a compression ratio. Provided are a first compression part compressing data using compressed sensing and a second compression part compressing observation coefficients coming from the first compression part using a method different from the method used in the first compression part. The first compression part performs random sampling using a sampling matrix optimized for compression by the second compression part. The sampling matrix is designed to minimize the differential value between the observation coefficients. The present technology can be applied to recording/reproducing apparatuses that capture, compress, record, and reproduce image data.

  • Patent number: 10790955
    Abstract: Techniques and examples of reservation of hybrid automatic repeat request (HARQ) acknowledgment (HARQ-ACK) resources in UCI in wireless communications are described. Accordingly, a UE determines how a HARQ-ACK is to be transmitted to a network node of a wireless network. The UE reserves HARQ-ACK resources among a plurality of resource elements (REs) for a two-bit HARQ-ACK based on a result of the determining. The UE then transmits the HARQ-ACK, having zero bit, one bit or two bits, to the network node in a physical uplink shared channel (PUSCH) using the reserved HARQ-ACK resources such that the PUSCH is punctured for the HARQ-ACK.

  • Patent number: 10783772
    Abstract: A system for delivering power to a load includes a master control unit (MCU) communicatively connected to a wireless network. A remote control circuit is electrically connected to the MCU. The remote control unit delivers a signal of a first voltage to the MCU when the remote control unit is not receiving a command signal from a remote controller, and deliver a signal of a second voltage to the MCU when the remote control unit is receiving a command signal from the remote controller. A relay unit is electrically connected to the load and to an output of the MCU. The MCU is programmed to selectively power the load by selectively passing control signals to the relay unit in response to commands received from the wireless network. When no signals are received from the wireless network, the remote control circuit may control the load, either directly or via the MCU.

  • Patent number: 10764101
    Abstract: A system and method for waveform modulation includes encoding input digital data at selected phase angles of an unmodulated sinusoidal waveform. The encoding includes selectively reducing a power of the unmodulated sinusoidal waveform at the selected phase angles in accordance with bit values of the input digital data so as to respectively define first, second, third and fourth data notches in the modulated sinusoidal waveform. An encoded analog waveform is then generated from a digital representation of the modulated sinusoidal waveform. The encoding is performed so that energies associated with the first and third data notches are balanced and energies associated with second and fourth data notches are also balanced. Each of the energies corresponds to a cumulative power difference between a power of the unmodulated sinusoidal waveform and a power of the modulated sinusoidal waveform over a phase angle range subtended by one of the data notches.

  • Patent number: 10756785
    Abstract: A radio network sub-tiles reference signals (RSs) within a set of resource elements (REs) such that each sub-tiled RS occupies less than a time and/or frequency and/or power extent of its respective RE. The set of REs are dispersed across both frequency bins and time slots according to a pre-defined grid; and transmitted. The user equipment (UE) uses that pre-defined grid to locate within that transmission the set of dispersed REs. The UE accumulates and combines at least one subset of the sub-tiled RSs and estimates therefrom a quality; then reports uplink an indication of that estimated quality. Examples of the RSs include channel state information RSs, beam RSs and beam refinement RSs. Advantages are particularly relevant for 5G new radio systems.
