International Classification:

G06T 120
G06F 1516

US Classification:

345506

Abstract:

A method and apparatus for synchronizing the execution of a sequence of graphics pipelines is provided. For a representative embodiment a sequence of graphics pipelines are connected in a daisy-chain sequence. Each pipeline operation can be controlled to operated in one of two modes. The first is a local mode where the pipeline outputs its own digital video data. The second is a pass-through mode where the pipeline outputs digital video data received from preceding graphics pipelines. The pipelines are configured to allow an application executing on a host process to select the next pipeline that will enter local mode operation. The pipeline that is selected to enter local mode operation asserts a local ready signal when it is ready to begin outputting its digital video information. Each of the pipelines monitors the state of a global ready signal. When the global ready signal becomes asserted it means that the pipeline that is selected to enter local mode operation is ready.

International Classification:

H02J 50/40
H02J 50/70
H02J 50/90
H02J 50/10

Abstract:

A machine implemented method includes alternately energizing multiple transmit coils in a first device, receiving indications of received signal strength at receive coils in a second device, selecting a first pair of coils including a first transmit coil and a first receive coil having the greatest received signal strength, and transferring energy from the first transmit coil to the first receive coil.

International Classification:

H01M 6/42
H01M 2/24
H01M 2/02
H01M 2/10

Abstract:

An electronic device includes a frame and a battery. The frame is configured to be worn on a user's body. The battery is supported by the frame and includes a first cell and a second cell in electrical parallel. The first cell has a first capacity and the second cell has a second capacity that is different from the first capacity.

Inventors:

Julian Binder - Sunnyvale CA, US
Daniel Chian - Los Altos CA, US

International Classification:

H02H 3/00
H02H 7/18

Abstract:

Techniques for enabling multi-pack and component connectivity detection are provided. In some configurations, individual PCMs can test the connectivity between components of a device without the need to operate the components. For example, PCMs configured in accordance with the present disclosure can test the connectivity between a motherboard, a display circuit, a camera, and a number of battery packs without the need to operate the motherboard, display circuit, camera, etc. In some configurations, conductors that are part of cables and connectors used to connect the components can be used to determine the state of one or more connections. When a signal that runs through the conductors meets one or more criteria, the PCMs of a device cause a predetermined delay prior to enabling one or more components. By testing the connectivity between components before each component transitions to an operational state, other problems caused by faulty connections can be mitigated.

International Classification:

H02H 3/10
H02H 7/18
H02H 5/04

Abstract:

An enhanced parallel protection circuit is provided. A system using separate battery packs in a parallel configuration is arranged with multiple protection circuit modules (PCMs). The PCMs are configured to detect fault conditions, such as over voltage, under voltage, excess current, etc. The PCMs can be configured to control associated switches and/or other components. When a fault condition is detected by an individual PCM, the individual PCM transitions to a fault state, and the PCM triggers an output causing one or more actions, e.g., causing a device to shut down or isolate one or more components. In addition, by the use of the techniques disclosed herein, the individual PCM can generate a control signal that causes other PCMs to transition to a fault state. The individual PCM can also receive a control signal from another PCM to cause the individual PCM to transition to a fault state.
