Abstract: A host assembly of a 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 communication device using a current wireless network via a first access point confirms availability of a second access point before breaking the current connection. To confirm availability of the second access point, the communication device sends a power management message that causes the first access point to store packets during the power management period. After the connection to the second access point is confirmed, the second session may be put on hold using the same technique while the connection to the first access point is restored, the stored packets processed and the connection closed. Then the connection to the second access point may be reactivated and further communication made through the second access point.

Abstract: In an example, a method includes determining, at a host device, a power state of a digital input/output device, and transmitting a clock signal having a first frequency from the host device to the input/output device responsive to a determination that the input/output device is in a lower power state. The method also includes determining, at the host device, that the input/output device has transitioned into a higher power state, and transmitting a clock signal having a second frequency from the host device to the input/output device responsive to a determination that the input/output device has transitioned into the higher power state. The first frequency is lower than the second frequency.

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.

Abstract: Methods, systems and computer program products are described for transferring aggregated data packets over an I/O interface from a host to a multiport embedded device. For example, a method includes receiving, by the device from the host, a single write command that (i) specifies two or more ports from among multiple ports of the device, and (ii) includes two or more data packets to be respectively written to the specified ports. The multiple ports of the device are mapped to corresponding locations of memory of the device. The method further includes saving, by the device in response to the single write command, the two or more data packets at two or more memory locations to which the specified ports are mapped. Additionally, the method includes sending, upon saving the data packets, a single notification to the host indicating that the device is ready to receive another write command.

Abstract: To satisfy the need for refitting the lighting of a vehicle without the need to modify the controlling system of the vehicle, the present invention proposes a lighting system which comprises an electrical element (110), configured to consume the received power and incapable of emitting light; a light source (130); and a controller (120), configured to receive a first signal indicating the working status of the electrical element (110) and control the light source (130) generating a first light and a second light, respectively, based on the first signal. By utilizing the signal indicating the working status of the electrical element (110), which element is used to replace another automotive lamp, the controller can control the light source (130) to mimic said another automotive lamp while performing its original function.

Abstract: Provided herein are systems and methods for detecting a compromised flow line in a laboratory instrument. In one embodiment, for example, the system includes: (1) a wash station in fluid communication with a sample probe; (2) a fluid line coupled to the wash station to withdraw fluid from the wash station and deliver the fluid to a waste tank; and (3) a vacuum transducer, coupled to the fluid line, to measure vacuum pressure per unit time within the fluid line. The vacuum pressure per unit time is then used to detect a compromised flow line (e.g., a clog, occlusion, opening, etc. in the flow line).

Abstract: In a method for controlling a wireless device assembly coupled to a host assembly, a clock signal is received at the wireless device assembly from the host assembly. The clock signal is supplied to an interface module in the wireless device assembly during a power save mode of the wireless device assembly and is used to operate the interface module. An initialization command is received at the wireless device assembly from the host assembly and is detected with the interface module. In response to detecting the initialization command, at least a portion of the wireless device assembly, other than the interface module, is activated.

Abstract: An interface system includes a secure digital (SD) driver module to communicate with an SD card over a bus, a secure digital input/output (SDIO) driver module to communicate with an SDIO card over the bus, and an input/output port.

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.

Abstract: A host includes an operating system segmented into a user space and a kernel space with a driver. The user space stores a firmware file and the kernel space includes memory. The driver is stored in the kernel space and performs download cycles to download the firmware file to the memory. The device driver, during a first download cycle, transfers a first block of data to the memory. During each download cycle performed subsequent to the first download cycle, the driver is configured to: identify first and second segments of the memory, where data including the first block of data was stored in the first segment during a previous download cycle; copy the data including the first block of data from the first segment to the second segment; and transfer a block of data of the firmware file, not previously stored in the memory, to the second segment.
