  • Patent number: 10327123
    Abstract: A system and method for Machine-to-Machine (M2M) communication over a transmission medium, including a novel random access protocol that is easy to implement, energy efficient, scalable and compatible with the limited-power and low complexity requirements of IoT devices. The proposed protocol utilizes a form of multiple hypothesis testing at the IoT gateway to determine the number of active IoT devices operating in the transmission medium to optimize the power levels of a Successive Interference Cancellation (SIC) receiver in order to distinguish between signals transmitted from different IoT devices on the same time and frequency. The use of beamforming exploits the power and spatial domains without excessively increasing the SIC power levels and address channel access delay problems by reducing the probability of collision and consequently lowering the average back-off delay.

  • Publication number: 20190179497
    Abstract: Methods, apparatus, and computer-readable media are described herein related to a user interface (UI) for a computing device, such as head-mountable device (HMD). The UI allows a user of the HMD to navigate through a timeline of ordered screens or cards shown on the graphic display of the HMD. The cards on the timeline may be chronologically ordered based on times associated with each card. Numerous cards may be added to the timeline such that a user may scroll through the timeline to search for a specific card. The HMD may be configured to group cards on the timeline. The cards may be grouped by multiple time periods and by various content types within each respective time period. The cards may also be grouped based on durations between the present/on-going time period and each respective time period.

  • Publication number: 20190140543
    Abstract: An AC capable power amplifier arrangement is realized that includes a buck converter with a power inductor, two buck switches, and alternately a buck-boost converter using four switches, each driving an output polarity steering set of four switches. The polarity steering switches convey the converter output current to output terminals that connect to a load with a capacitor connected in parallel. A differential receiver is connected to the output terminals to provide negative feedback. A mixer receives an input voltage signal, an output of the differential receiver, and output from a triangle wave generator. A set of two comparators for buck amplifier conversion, or four comparators for buck-boost amplifier conversion, each receives an output of the mixer. Each of the comparators produces a respective output for driving the converter switches through simple steering logic interfaces between the comparators, the converter components and a polarity steering output stage.

  • Publication number: 20190041896
    Abstract: A band-pass clock distribution circuit includes a clock tree circuit including at least one clock buffer circuit. The clock tree circuit may be configured to receive a first clock signal from a clock generator circuit and to generate a second clock signal based on the first clock signal. A band-pass filter may be configured to receive the second clock signal and to provide a third clock signal to one or more load circuits. The band-pass filter includes a filtering resonant network including a first inductor and a second inductor coupled to one another at a center tap. The filtering resonant network is configurable to resonate with a parasitic capacitance associated with the one or more load circuits. A portion of the band-pass filter is integrated with the clock tree circuit.

  • Patent number: 10198292
    Abstract: A system, for example, an online system or a database system schedules requests received for execution. The system maintains consumer groups and receives a measure of amount of resources allocated for each consumer group. The system maintains a measure of accumulated elapsed time of execution of requests received from each consumer group. If the system determines that resources are available for executing a request, the system selects a request for execution from a consumer group based on the measure of accumulated elapsed time for processing queries for the consumer group and the measure of amount of resources allocated for the consumer group. The system maintains relative cumulative elapsed times of queries across consumer groups in the same ratio as the allocated share for the consumer groups. Accordingly, the system schedules requests such that each consumer group approaches its allocation of resources compared to other groups smoothly over time.

  • Publication number: 20190036541
    Abstract: A hybrid digital-to-analog converter (DAC) driver circuit includes a current-mode DAC driver, a voltage-mode DAC driver, and a combination circuit. The current-mode DAC driver may be configured to receive a first set of bits of a digital input signal and to generate a first analog signal. The voltage-mode DAC driver may be configured to receive a second set of bits of the digital input signal and to generate a second analog signal. The combination circuit may be configured to combine the first analog signal and the second analog signal and to generate an analog output signal. The DAC driver circuit may be terminated by adjusting resistor values of the voltage-mode DAC driver. The current-mode DAC driver and the voltage-mode DAC driver are differential drivers, and may be configured to operate with a single clock signal.

  • Patent number: 9749086
    Abstract: In various embodiments, the present invention presents a physical layer (PHY) authentication technique for implantable medical devices (IMDs) that does not use existing methods of cryptology. Instead, a friendly jamming mechanism is established and malicious attempts by adversaries are prevented, without sharing any secured information, such as secret keys. In addition to ensuring authentication, the invention also provides advantages in terms of decreasing processing complexity of IMDs and enhances overall communications performance.

  • Patent number: 9606415
    Abstract: A super-oscillatory lens (10) having a pre-defined pattern to spatially modulate the light beam in amplitude and/or phase which has a blocking element (6) formed integrally with the lens, or as a separate component adjacent to the lens, which is opaque to the light beam to cause diffraction of the light beam around the blocking element and formation of a shadow region (20). The lens and blocking element focus the light beam to form an elongate needle-shaped focus (15) in the shadow region (20). In any application in which it is necessary to scan a small spot over a surface, compared with a conventional objective lens focus the elongate shape of the focus relaxes the requirement on a feedback loop to maintain a constant separation between a scan head and a surface being scanned. The elongate shape is also ideal shape for materials processing applications.

  • Patent number: 9511706
    Abstract: A restraining device including a bag filled with a ballast and sealed on all sides. When filled with predetermined amount of ballast, the restraining device is flexible and conforms to the shape of a cargo and a vehicle cargo area in a horizontal and or vertical dimension. The restraining device secures cargo in a vertical dimension while creating extra friction between the cargo and a cargo bed to prevent or reduce horizontal movement of the cargo. The restraining device interacts with cargo in a solely horizontal function by wrapping it around the horizontal base perimeter of the cargo. In this case, the friction between the restraining device and the cargo bed creates a barrier for the cargo thereby preventing or reducing horizontal movement of the cargo.
