摘要： An electronically steerable antenna system includes a plurality of panels that are coupled together to form an N-sided polygon. Each panel includes a plurality of microstrip conductor patches forming a phased array antenna. In a first embodiment that includes beam steering, each panel can selectively transmit or receive in a direction that is either perpendicular to the panel, or to the left or right of perpendicular, depending upon relative delay line lengths applied to the left and right antennas. A second embodiment omits the beam steering capability for each panel and simply enables only one of the N different panels to be employed for transmitting or receiving a radiofrequency signal in a direction perpendicular to the panel. PIN diodes are preferably used for selecting the panel that is active, and in the first embodiment, for selecting the delay lines used.

摘要： Described is a technology by which a computer pointing device (generally a mouse but alternatively a game controller or remote control device) may be worn on the hand and operated without needing to contact a mousing surface. Gyroscopic-based sensors convert the wearer's hand and wrist movements to signals which are sent to a host computing device such as a conventional personal computer, a gaming console, an electronic appliance, and so forth. The data received from the pointing device may be used to move a cursor or the like, and other received data may correspond to left and right mouse clicks, scrolling operations, and so forth. A user-controlled enable switch/sensor selectively activates or deactivates the pointing device so that only intended movements result in data transmission. Gestures may also be sensed and used to trigger defined functions.

摘要： An interface enables an RF signal, a DC power signal, and a data signal to be conveyed between two devices over a single RF cable. In an exemplary application of this invention, a steerable antenna system is coupled to a wireless adapter for use in a wireless network. The steerable antenna includes a plurality of panels that can be selectively activated in response to the data signal, which also determines a direction in which an RF signal is transmitted or received by a selected panel of the antenna. Low pass filters in each device isolate the DC power supply and the load from the other two signals. High pass filters isolate the radio in the wireless adapter and the antenna array from the DC and data signals. The data signal is preferably encoded into a Manchester format that passes through a bandpass filter provided in each device.

摘要： A wireless access point is equipped with both an omnidirectional antenna and a directable antenna that can be selectively directed to any of a plurality of directional spaces overlapping the network space served by the omnidirectional antenna. The directable antenna is directed to an optimal directional space for a client when the access point is communicating with the client at a high data rate. The access point can intermittently exchange information with other clients using the omnidirectional antenna. The omnidirectional antenna enables broadcast signals to be transmitted to any client in the entire network space, but at a lower data rate. A preferred data rate and an optimal client directional space are re-determined periodically or as necessary based on parameters such as the data rate, signal strength, and rate of success in communicating data.

摘要： A wireless device is coupled to a multi-sector antenna that includes a plurality of different sectors, any of which can be activated to transmit and receive in a desired direction specific to that sector. Optionally, an omnidirectional antenna is included for initially establishing a wireless connection with another wireless device, such as an access point. A parameter indicative of signal quality, such as throughput or received signal strength indication (RSSI) is determined by polling with each antenna sector to establish a prioritized candidate list. If a receive Trigger becomes active in response to a parameter falling below a threshold level, a new candidate sector is selected from the current list based upon a next-best signal quality. The directionality of the multi-sector antenna provides a substantially higher data rate compared to that of the conventional omnidirectional antenna.

摘要： An active matrix for a capacitive multiple touch sensing device is disclosed. One embodiment comprises one or more active matrix capacitive touch sensing pixels that each include a capacitor and a thin film transistor, wherein a voltage can be applied to the thin film transistor to address the capacitor. In this way, the thin film transistor can operate as a switch to apply an alternating current to the capacitor, and the capacitor's capacitance can be measured in relation to the alternating current and an externally applied electric field.
