Abstract: Systems and techniques are provided for performing wireless communications. In some aspects, an access point (AP) determines if buffered data traffic is available that will be advertised to one or more wireless communication devices using a beacon frame scheduled for broadcast by the AP. The AP broadcasts a pre-determined frame in response to determining buffered data traffic is not available, and the AP may skip broadcasting an upcoming beacon frame associated with the pre-determined frame. For example, the AP broadcasts the upcoming beacon after broadcasting the pre-determined frame when there is a change of configuration or when a resynchronization interval associated with the one or more wireless communication devices has been exceeded.

Abstract: Systems and techniques are provided for performing wireless communications. In some aspects, an access point (AP) determines if buffered data traffic is available that will be advertised to one or more wireless communication devices using a beacon frame scheduled for broadcast by the AP. The AP broadcasts a pre-determined frame in response to determining buffered data traffic is not available before broadcasting the beacon frame. A wireless communication device exits a low-power mode to receive an upcoming beacon frame or receive a pre-determined frame broadcast by the AP. Based on receiving the pre-determined frame, the wireless communication device determines that the upcoming beacon frame does not advertise buffered data traffic addressed to the wireless communication device and returns to the low-power mode after decoding at least a portion of the pre-determined frame.

Abstract: A method and apparatus for measuring the viscosity of a sample solution. A capillary (2) having first and second spaced apart detection windows (W1,W2) is filled with a carrier solution. A plug (4) or a continuous volume (4) of a sample solution is injected into the first end of the capillary (2) and pumped through the capillary (2) at a first pump pressure passing through the first and second detection windows (W1,W2). At least part of each detection window (W1,W2) is illuminated with a light source. Light from the light source passing through the carrier solution or the sample solution at each detector window (W1,W2) is detected using an array detector (6) comprising a two dimensional array of detector locations which generates an array detector output signal indicative of the profile of light absorbance of the sample solution plug (4) or flow front (4) passing through each detection window (W1,W2).

Abstract: A multi-user vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and one or more central hosts. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of DataPoint Records (DPRs) in an on-board non-volatile (e.g. flash) memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. Although the DPRs are stored in permanent storage on the gateway, they are deleted from permanent storage on the gateway after they are successfully uploaded to the central hosts. The gateways are shared, and communicate with the central hosts over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to selected central hosts.

Abstract: Devices and methods for identification, authentication, and quantification of one or more covert markers in a material are disclosed. A device includes a microfluidic cell, a liquid transfer system, and a detector system and is an integrated unit providing an automated, in-line process for identifying one or more materials containing at least one latent marker that may transform into an active form. The microfluidic cell is for receiving a material containing a latent marker and has at least one inlet for receiving one or more liquids and one or more outlets through which liquids exit. The liquid transfer system is operably connected to the microfluidic cell and delivers liquids to the microfluidic cell. The detector system is proximate to the outlets for detecting the active form of the marker. With the device, a number of independent processing and analytic steps are combined onto a single, portable unit.

The packet includes a subpacket and a check sequence. The method further includes verifying the integrity of the subpacket, the verifying at least using the check sequence. The method further includes, in the case that the subpacket fails the verifying, reducing the power consumption of at least one component in the first wireless station for a time interval.

Abstract: A method for automatic hidden node detection that includes observing frame exchange sequences that conform to a MAC standard such as the IEEE 802.11 standard. The method includes detecting a hidden node upon receiving a response frame without previously receiving the frame causing the response. Similar conclusions may be drawn from longer frame sequences. When a hidden node has been detected with reasonable certainty, a hidden node report is sent to a hidden node manager. In one embodiment, the hidden node manager is centralized, and in another, the management function is performed in a distributed manner. Upon receiving a report, the hidden node manager automatically invokes hidden node avoidance measures by sending one or more action frames. In another embodiment, the hidden node manager turns on a hidden node mitigation method. In the case of the IEEE 802.11 standard, the hidden node manager turns on the IEEE 802.11 hidden node mitigation method based on RTS/CTS exchange.

Abstract: A method and apparatus for synchronizing a local clock value in a wireless receiver receiving a data unit containing synchronization information. The method includes receiving a first data unit containing synchronization information, extracting the synchronization information from the received first data unit, copying a local free-running clock at a known reference point in time relative to the time the first data unit was received to generate a local timestamp; and calculating an offset to the free-running clock using the extracted synchronization information and the local timestamp, the calculating in non real-time, such that the sum of the calculated offset and the value of the free-running clock provides a local clock value that is approximately synchronized in time. The apparatus implementing the method is part of a node of a wireless station, and provides a time synchronization function, typically at the MAC layer.

Abstract: A vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and a central host. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of Data Point Records (DPRs) in an on-board flash memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. The gateways communicate with the central host over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to the central host. Databases in the gateways as well as in the central host are maintained and synchronized to track received DPRs by sequence number and originating VIU. In conjunction with specific protocols, all DPRs are thus collected reliably, even though communication with a vehicle may be intermittent. Efficient use of WiFi bandwidth is made by avoiding the unnecessary collection of duplicate DPRs.
