Abstract: A method for location aware networking in a wireless ad-hoc network having a plurality of wireless nodes in a geographic area comprising: dividing the geographic area into a plurality of grids; determining a location of a particular wireless node; determining a corresponding grid where the particular wireless node resides; determining a cluster head for the corresponding grid; connecting corresponding wireless nodes in the corresponding grid to the cluster head, wherein the cluster head of the corresponding grid periodically gather data from the corresponding wireless nodes, aggregate the data and transmits the data to a gateway; and coupling the cluster head of the corresponding grid to cluster heads of each of the plurality of grids forming a pathway to the gateway, the cluster head of the corresponding grid transmitting the data through the pathway or directly to the gateway.

Abstract: A method for forming a collaborative wireless sensor array comprising: connecting a plurality of wireless sensor nodes together, wherein each of the plurality of wireless sensor nodes wirelessly communicate with one another; collecting data by the plurality of wireless sensor nodes; forming metadata on the data collected by each of the plurality of wireless sensor nodes; sharing the data and metadata with the plurality of wireless sensor nodes; and fusing the data and metadata to perform a task.

Abstract: A method for interference avoidance when transmitting a message in a wireless system comprising: dividing a frame into a plurality of time slots, wherein a first plurality of time slots allocated as Time Division Multiple Access (TDMA) time slots and a second plurality of time slots allocated as contention slots; transmitting a message in a designated TDMA time slot by a corresponding wireless node assigned to the designated TDMA time slot if the designated TDMA time slot is idle; and transmitting the message in a contention slot if the designated TDMA time slot is busy.

Abstract: Embodiments disclosed herein include devices and methods pertaining to medical lead connectors. According to various embodiments of the disclosed technology, disclosed is a lead connector that may include a base member; a flexible circuit configured to support electrical connections; and a casing that includes a bottom casing and a detachable cover member to be placed on top of the bottom casing. The bottom casing may include an array of slot openings to provide access to a surface of the flexible circuit and the lead connector may also include an array of electrode contacts positioned on top of the slot openings. Furthermore, a lead may be configured to be inserted through the lead connector via an opening on both ends of the cover member, wherein the lead pushes the ball contacts downward allowing the ball contacts to make electrical contact with the flexible circuit through the slot opening of the bottom casing.

Abstract: A low profile light comprises mating front and back housings (12, 14), between them defining the thickness of the light. An attachment is provided on the back housing, whereby the light is attachable to a base on which the light is to be mounted. A circuit board (16) mounts circuit elements (36) and interconnecting conductive tracks to which LED devices (28) are connected. The board is enclosed and sandwiched between said front and back housings. The front housing is transparent or translucent to transmit light emitted from the LED devices. The circuit elements and LED devices are arranged to be powered by AC mains electricity. The thickness of the light is no greater than 10% more than the sum of the thicknesses of said front and back housings and the maximum 15 dimension of a minimum power-rating two-core mains electricity power cable (18). That is, it is less than 10 mm thick.

Abstract: A method of rocking a wheeled infant carrier (30) comprises using a rocking device (10) having a pair of discrete units (12,14). Each unit has a ground-engaging base (18a,b) and a platform (16a,b) supported thereon through bearings for movement relative to the base in a first direction. A drive one (12) of the units has a motor in a housing (20) arranged to drive the platform (16a) of the drive unit relative to its base back and forth in said first direction. A first wheel (34) of the carrier (30) is placed on the drive unit and a second wheel (32) on the second, slave unit (14), with the axes of rotation of the wheels being arranged parallel said first direction. The motor is operated to rock that end of the carrier that is supported by those wheels from side to side.

Abstract: An electronics testing assembly includes a housing, a tester assembly, and an activation assembly. The housing is sized to retain the activation assembly and at least one electronics testing device. The tester enclosure is configured to house a plurality of tester connector interfaces that are mounted to a first connector plate. The activation assembly includes an actuator assembly and a plurality of activation connector interfaces mounted to a second connector plate. The actuator assembly is configured to move the second connector plate between a lowered vertical position and a raised vertical position within the housing while maintaining a fixed orientation of the tester enclosure relative to the housing. In the lowered vertical position the activation connector interfaces are spaced apart from the tester connector interfaces, and in the raised vertical position the activation connector interfaces are engaged with the tester connector interfaces to create an electrical connection.

Abstract: A method of rocking a wheeled infant carrier (30) comprises using a rocking device (10) having a pair of discrete units (12,14). Each unit has aground-engaging base (18a,b) and a platform (16a,b) supported thereon through bearings for movement relative to the base in a first direction. A drive one (12) of the units has a motor in a housing (20) arranged to drive the platform (16a) of the drive unit relative to its base back and forth in said first direction. A first wheel (34) of the carrier (30) is placed on the drive unit and a second wheel (32) on the second, slave unit (14), with the axes of rotation of the wheels being arranged parallel said first direction. The motor is operated to rock that end of the carrier that is supported by those wheels from side to side.
