Abstract: Proximity based systems and methods that are implemented on an electronic device are disclosed. The method includes sensing an object spaced away and in close proximity to the electronic device. The method also includes performing an action in the electronic device when an object is sensed.

Abstract: A power adapter for a peripheral device such as portable electronics device is disclosed. The power adapter includes a housing that contains electrical components associated with the power adapter. The power adapter also includes a data port provided at a surface of the housing. The data port is configured to provide external power to the peripheral device.

Abstract: A low power, single master, variable clock rate, daisy-chainable, serial bus connects a bus dispatch (master) to a chain of one or more daisy-chained peripheral devices (slaves). The bus has a bidirectional serial data line, a bidirectional clock line, unidirectional interrupt line, power and ground lines. A method for configuring the bus includes detecting connection and disconnection of a peripheral device to the bus. In the method, a last peripheral device on the bus is assigned the second status and all other peripheral devices on the bus are assigned the first status. Each peripheral device assigned the first status is configured to pass therethrough an interrupt signal on the bus. The last peripheral device is configured to invert an interrupt signal on the bus from a peripheral device that is newly attached to the bus. A peripheral device newly connected to the bus generates an interrupt signal that is inverted by the last peripheral device and transmitted over the bus to a host computer for the bus.

Abstract: A low power, single master, variable clock rate, daisy-chainable, serial bus connects a bus dispatch (master) to a chain of one or more daisy-chained peripheral devices (slaves). The bus has a bidirectional serial data line, a bidirectional clock line, unidirectional interrupt line, power and ground lines. All bus transactions over the bus occur under bus dispatch commands. If a peripheral device interrupts the bus dispatch, bus dispatch issues commands over the bus to determine which device caused the interrupt and what service is being requested by the device. The bus dispatch may then turn control of the data and clock lines over to the peripheral device for a limited amount of time depending on the service requested. New peripheral devices can be connected onto the bus and unused peripheral devices can be disconnected from the bus while the bus is operating without causing a bus failure. Similarly, bus dispatch may enter a low power sleep mode from which it may be awakened by a peripheral device.

Abstract: A low power, single master, variable clock rate, daisy-chainable, serial bus connects a bus dispatch (master) to a chain of one or more daisy-chained peripheral devices (slaves). The bus has a bidirectional serial data line, a bidirectional clock line, unidirectional interrupt line, power and ground lines. Each peripheral device includes a first bidirectional signal line, a second bidirectional signal line coupled to the bus clock and data lines, respectively, and an interface circuit coupled to the first and second bidirectional signal lines. The interface circuit includes a first buffer circuit coupled to the first and second bidirectional signal lines, and a second buffer circuit coupled to the first buffer circuit.
