Abstract: According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing ultra-wideband (UWB) antenna array systems respective mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.

Abstract: Systems and methods for monitoring air quality of a geographic area are provided. Digital signage units include an electronic display and an air quality monitoring device located along an open loop pathway for ambient air. A monitoring subsystem receives air characteristic measurement data from the air quality monitoring devices of the digital signage units, which are installed at discrete locations within the geographic area, and subsequently generates a data summary of air characteristic measurements from the air characteristic measurement data from some or all of the digital signage units.

Abstract: A method is provided for wireless communication between a wireless remote control device comprising a peripheral device and a controller on a materials handling vehicle comprising a central device. The method may comprise: polling via a plurality of connection event requests, by the central device, communicated with the peripheral device with which the central device is paired, the peripheral device comprising one or more activatable switches. Based on the status of one or more activatable switches, the peripheral device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one communication operating mode of the peripheral device, wherein each reply message is indicative of the status of the one or more activatable switches. Calculating, by the central device, a number of missed messages.

Abstract: A system and method for using timing data from an incomplete packet to more accurately determine the position of a transmitter in a workspace is provided. A radio signal packet comprising a header portion containing timing data, and a data portion, is transmitted from a transmitter. Upon successful receipt by at least one receiver in a known location, header portions from incomplete receptions at other receivers are correlated to the transmission. Timing data from the correlated, and incomplete, receptions are then used by a location determining algorithm to improve position accuracy and extend the range of the system.

Abstract: A hole saw with ejector configured to eject a plug upon rotating a collar located about the cutting blade. The hole saw with ejector has an annular cutting blade with one or more slots angled with respect to a longitudinal axis. The ejector forms a sub-assembly with a plug stop located inside the cutting blade, an ejector collar located about the cutting blade, and one or more attachments through the one or more slots that connect the plug stop to the ejector collar and form a track and/or rail system whereupon rotation of the ejector collar moves the sub-assembly backward and forward to eject a sawn plug from the hole saw.

Abstract: A system is disclosed in which a data processing device is completely synchronized with a messaging service. One embodiment of the system comprises a wireless data processing device; a messaging service to maintain messages and other information on behalf of a user; and synchronization logic for maintaining synchronization of the messages and other information between the wireless device and the messaging service.

Abstract: A surgical clip applicator for applying surgical clips to body tissue includes an elongated ram housing that has proximal and distal ends and at least partially encloses a ram. A trigger housing includes a trigger that has an open position and a closed position. The trigger housing is mounted to the proximal end of the ram housing. The ram extends partially into the trigger housing and is operatively connected to the trigger. The trigger is spaced a first distance from the trigger housing in the open position and spaced a second distance from the trigger housing in the closed position. The first distance being larger than the second distance. A cartridge is removably mounted into the ram housing. The cartridge includes a plurality of the surgical clips. A retaining mechanism retains the trigger with respect to the trigger housing between the open and closed positions.

Abstract: A system is described in which, under certain conditions, a wireless data processing apparatus and/or the service to which the apparatus communicates, will enter a batch processing mode. Under the batch processing mode, the apparatus and/or service will combine a series of message transactions (e.g., message viewings, message deletions, . . . etc) before synchronizing with the service and/or apparatus, respectively. Various types of batch processing parameters may be set to determine whether the system should enter batch processing mode and/or how batch processing should be performed once batch processing mode has been entered.
