Abstract: Various implementations include approaches for establishing a Bluetooth (BT) connection between devices. One example approach includes: in response to a BT trigger at a first BT device, attempting to determine a received signal strength indicator (RSSI) from a set of additional BT devices paired to the first BT device; if an RSSI from a first additional BT device is a highest RSSI from the set and exceeds an RSSI from a second additional BT device with a second-highest RSSI by a threshold, selecting the first additional BT device for connection with the first BT device; and if a difference between the RSSI from the first additional BT device and the RSSI from the second additional BT devices does not exceed the threshold, selecting either the first additional BT device or the second additional BT device for connection based on a BT connection hierarchy.

Abstract: Various implementations include approaches for establishing a Bluetooth (BT) connection between devices. One example approach includes: in response to a trigger at a first BT device, attempting to determine a received signal strength indicator (RSSI) of a second BT device paired to the first BT device, the second BT device having a highest priority on a list of one or more BT devices paired to the first BT device; in response to determining the RSSI for the second BT device, determining if the RSSI of the second BT device satisfies a threshold; and in response to determining that the RSSI of the second BT device satisfies the threshold, attempting to establish a BT connection between the first BT device and the second BT device.

Abstract: An intentional presence system in accordance with the present invention includes a transmitting device at a first physical location that is responsive to a command intentionally initiated by a first individual at the first physical location to develop a presence signal intended for a second individual at a second physical location. The intentional presence system further includes a receiving device located at the second physical location which is receptive to the presence signal and which is operative to generate an indication to the second individual of the first individual's presence with respect to the transmitting device.

Abstract: The present invention teaches methods and apparatus for social interaction allowing users to communicate at their leisure (asynchronously or “semi-synchronously”) by providing simple, flexible access to a persistent, shared space. For example, an electronic communication system according to one embodiment provides a shared persistent data space to a plurality of clients. This system comprises a server and at least two input/display units (IDUS) which clients use to access shared persistent data in the form of group boards. The group boards store discrete notes in a group database made accessible to all members of the group. In order to allow clients to select a desired group, each IDU includes an input detection space operable to receive user input indicative of a request to access a specific group.

Abstract: A signal synthesizer is provided for producing pulses simulating characteristics of echo pulses generated during ultrasonic scanning so that the simulated pulses can be used in the calibration of equipment for processing the outputs of ultrasonic transducers. The synthesizer produces an envelope signal of selectively variable amplitude and rise and fall time and multiplies this envelope respectively with a high frequency pulse train and a substantially zero amplitude signal in a dual matched multiplier so that the subtractively combined outputs of the multiplier are free of unwanted feedthrough components introduced by the mulitplier.
