Abstract: A high efficiency turf maintenance apparatus having low power consumption and good cutting performance is presented herein. A multi-blade blade assembly is disclosed to reduce power consumed in driving the blade assembly and enhance longevity of a dischargeable power supply. In some aspects described herein, a first blade of the multi-blade assembly can have a first length that is greater than a second length of a second blade. Further, the first blade or the second blade can be substantially bilaterally symmetric about a rotation axis of the multi-blade assembly. In alternative or additional aspects, the second blade can provide lift within a deck of the high efficiency turf maintenance apparatus to propel turf clippings from within the mow deck through a discharge opening therein.

Abstract: An unmanned aerial vehicle can be configured to adjust a beam direction, provide path information, act as a base station, act as a cluster head, include an improved directional antenna or array of directional antennas, communicate in a collaboration using belief propagation, receive communications from a serving station aiding in navigation or improved signal performance, or the like.

Abstract: A method for determining what input should be accepted by a touch sensor after intentional and accidental lift-offs and slide-offs occur when gesturing or performing a function on the touch sensor by a finger or multiple fingers.

Abstract: A cane with grasping fingers. The cane includes a hollow shaft having a first end and a second end, a grasping mechanism within the first end of the shaft, and a release mechanism adjacent to the second end of the shaft. The release mechanism includes a handle, a trigger within the handle, and a release button. Pressing the release button extends the trigger beyond the handle and extends the grasping fingers beyond the first end of the shaft so that the grasping fingers are separated by a first distance. Squeezing the handle retracts the grasping fingers and reduces the distance between the grasping fingers to a second distance less than the first distance. Squeezing the handle so that the grasping fingers are fully retracted into the first end of the shaft results in the trigger and the grasping mechanism being locked into place until the release button is pressed again.

Abstract: A timer assembly is slidably received within a channel support (120) for mounting on a work surface (280). The timer assembly (200) includes a set of controls (204). The assembly (200) is connectable to a simplex receptacle (142) for controlling the times at which the simplex receptable (142) is enabled and disabled. A remote control device (286) is operable by a user for transmitting spatial signals to the timer assembly (200) so as to control the timer assembly (200).

Abstract: A camera interface module is disclosed. The camera interface module has a first connector on one side configured to couple with a camera dock. The camera interface module has a second smaller connector on a second side configured to couple to a camera. The camera interface module has a standard input/output (I/O) connector and a power jack on a third side.

Abstract: A digital camera is disclosed herein. An embodiment of the digital camera comprises a display, wherein previously captured images are displayable on the display when the camera is in a first mode. Images of scenes that are capturable by the camera are displayable on the display when the camera is in a second mode. A touch pad is located proximate the display. Contact of a stylus on the touch pad causes the display to display different previously captured images when the camera is in the first mode. At least one icon representative of at least one function is displayable on the display when the camera is in the second mode. Contact by a stylus on the touch pad proximate the icon causes the at least one function to activate.

Abstract: Devices sharing battery charging resources coordinate use of a high-current charging mode through use of a message protocol between the devices. While a high-priority device is using the high-current charging mode, the other devices may continue charging in a reduced-current charging mode.

Abstract: A radio telephone capable of being operated in more than one radio telephone system, comprising communication means respectively associated with each of the more than one radio telephone system, monitoring means for monitoring signals of the more than one radio telephone system, and selection means responsive to said monitoring means for automatically selecting and re-selecting respective said communication means in accordance with the signals of one of the more than one radio telephone system fulfilling at least one predetermined criterion. The predetermined criterion can be based on a number of features such as received signal strength, access rights, system requests, least BER or frame error rate and user velocity.

Abstract: A radio telephone (200) is operable in a cordless telephone system or in a cellular telephone system. The telephone (200) incorporates circuitry to detect user velocity so that when the user travels more quickly the telephone automatically transfers from cordless mode, which is the preferred mode, to cellular mode. This prevents the degeneration in communication quality which frequently occurs when a user of a cordless system travels faster than walking pace.

Abstract: A radio telephone automatically hands over a call from one radio telephone system to another radio telephone system. Communication with respective radio telephone systems may be simultaneously continued during handover until the handover is complete, or communication with one radio telephone system ceases before communication with the other radio telephone system commences. Delays between signals of different radio telephone systems which would cause audible interference are inhibited by FIR filtering and/or dynamic time-warping. If an handover fails then communication with the original radio telephone system is restarted or continued.
