International Classification:

G08C 17/00

US Classification:

370311

Abstract:

In a method and apparatus for providing memory efficient filtering of a received broadcast signal, filter expressions are compared to packet data in the broadcast signal and by a wireless device assembly to determine if a match exists. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. Upon finding a filter match, the wireless device assembly selectively communicates the received packet data to the host assembly for packet decoding and analysis. If the host assembly is in a sleep mode, the wireless device assembly may send a wakeup signal to the host assembly prior to transmitting the packet data.

US Classification:

455574, 4551271, 4551275, 4553431, 4553435

Abstract:

In a method and apparatus for controlling operation of a wireless device, a host assembly of the wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.

Abstract:

A host assembly is communicatively coupled to a wireless device assembly via a first interface and via a second interface. A first signal is received at the wireless device assembly from the host assembly. The first signal indicates a request for the wireless device assembly to enter a host sleep mode of operation. In response to receiving the first signal, the wireless device assembly transmits a third signal to the host assembly, wherein the third signal indicates entry into the host sleep mode of operation. Subsequent to transmitting the third signal to the host assembly via the first interface, the wireless device assembly enters into the host sleep mode of operation. While in the host sleep mode of operation, the wireless device assembly transmits, via the second interface, the second signal, and, after transmitting the second signal to the host assembly, exits the host sleep mode of operation.
