  • Patent number: 9426745
    Abstract: A filter expression is received at a wireless device assembly of a communication device. While a host assembly of the communication device is in a sleep mode, the wireless device assembly receives a signal having packet data, and determines whether the packet data contains a data pattern indicated by the filter expression. If the packet data contains the data pattern, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. If the packet data does not contain the data pattern, the wireless device assembly does not communicate the wakeup signal to the host assembly.

  • Patent number: 9332496
    Abstract: In accordance with the invention, a method, system and apparatus for saving power consumed by a station in an ad hoc wireless network are presented. The method comprises transmitting or receiving a signal by a station in the ad hoc wireless network during a beacon interval. The station enters a power saving doze state immediately following the transmission or reception of the signal and prior to the end of the beacon interval. Additionally or alternatively, the station may enter power saving doze state following a timed period, according to a counter, or according to a periodic pattern.

  • Patent number: 9185653
    Abstract: In a method and apparatus for providing memory efficient filtering of a received broadcast signal, a wireless device assembly compares a filter expression to packet data in the broadcast signal to determine whether the packet data contains a particular bit pattern indicated by the filter expression. 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. If the host assembly is in a sleep mode, and if the packet data contains the particular bit pattern indicated by the filter expression, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. On the other hand, if the packet data does not contain the particular bit pattern indicated by the filter expression, the wireless device assembly does not communicate the wakeup signal to the host assembly.

  • Patent number: 8863148
    Abstract: A network interface includes a firmware module that generates a first message based on a first print macro call and a memory module that stores the first message. The first message comprises a subset of data indicative of the first print macro call.

  • Patent number: 8675531
    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.
