Abstract: In one embodiment, a client computing device stores a plurality of digital media files. For each digital media files, the client computing device stores data identifying a geographic location associated with the digital media file. When the client computing device receives a request to view digital media files through a graphical user interface, the client computing device uses a GPS receiver to determine a geographic location of the client computing device and an electronic compass circuit to determine an orientation of the client computing device. Based, at least in part, on the location and orientation of the client computing device, the client computing device identifies a plurality of particular geographic locations that are associated with one or more digital media files. The client computing device displays icons corresponding to the plurality of particular geographic locations, ordered by a distance from the client computing device to each of the location.

Abstract: Disclosed are systems and methods which provide a busy tone or signal for use in communication collision avoidance in a wireless network, such as a WLAN, a cellular network, or other point-to-multipoint wireless network. An intelligent busy tone generator, upon the proper conditions, transmits a busy tone or signal to one or more wireless device which may otherwise be hidden from particular communications. According to embodiments the busy tone mimics a carrier sequence of an actual transmission to facilitate the wireless devices recognizing the channel as busy. Because the original uplink packet may be interfered by transmission of a busy tone carrier-sense sequence, embodiments are provided with interference cancellation capability. Interference cancellation circuitry of embodiments may operate in a plurality of modes, including a training mode (including an online training mode, an offline training mode, and a hybrid or combined mode) and an operating mode.

Abstract: A two-way self-lock paper shredder has a functional switch (11), a shredding mechanism (10), a control circuit power source (2) electrically connected to the said functional switch (11), as well as the following control circuits: a CPU (1), a motor-driving circuit (8), a reverse detection circuit (9), a paper-in detection circuit (5), and an unlocking circuit (4). If there is neither an input of paper-in signal nor an input of reverse signal after the paper is shredded, the said paper-in detection circuit (5) will transfer a self-lock signal to said CPU (1) and then the CPU (1) begins timing. When the duration of said self-lock signal exceeds the preset value, the CPU (1) will shut off the motor-driving circuit (8) and the paper shredder will be self-locked. The aforesaid unlocking circuit (4) contains an unlocking key, and reset of the said unlocking key can unlock the paper shredder. The present utility model enhances the safety of the paper shredder efficiently, so as to avoid unnecessary hidden trouble.

Abstract: A multi-stage pedal valve structure relates to a flow regulator on the valve opening located between the two compartments inside the body of the one-way pedal valve. The device includes a valve jacket, a piston rod, a graduating disc and a spring, while the valve jacket possesses a concave channel guide and a one-way tilting wedge. The graduating disc is a cylindrical unit on the opposite of the valve jacket. The piston rod comes in the form of a trapezoid, of which the outer section increases from top to bottom, and the middle section of the piston rod features circular channels, of which the end and the lower section come in increasing pitches and the perimeter of the lower section comes with slant blocks in reduced numbers and in even numbers in proportion to the channels on the valve jacket. The device keeps water from flowing.

Abstract: A shell for containing infrared light detector. The shell has a focusing lens with a periphery through which a number of holes are formed and a panel molded from molten plastic. When the panel is being molded, the molten plastic flows through the holes so that the portion of the plastic functions as a number of latches inserted through the holes.

Abstract: A multimovable plastic lamp fixture. In the preferred embodiment, the lamp fixture includes a pair of lampholders for supporting a pair of floodlights or the like. Each of the lampholders are attached to a base by means of a ball and socket-type joint. The ball joint is located off-center and provides spherical positioning of the lights. A gasket located in the interior of each socket prevents moisture from entering the base and, in addition, maintains each lampholder in position due to friction. The ball and socket joint includes a knee ball cover having a semi-spherical surface for engaging the ball joint. Tabs located on the outer surface of the knee ball cover limit the rotational movement of each lampholder with respect to the base.

Abstract: A motion sensor lighting control includes a hemispherical mounting plate having a pair of first circular apertures and a second circular aperture, a pair of lamp holders for receiving lamps therein rotatably mounted on the first circular apertures by a pair of first swivel devices, a sensor housing for receiving an infrared sensor rotatably mounted on the second circular aperture by a second swivel devices. The first swivel devices and the second swivel device are such arranged to let the lamp holders and the sensor housing to be manually rotated in universal orientations, yet limiting the rotation angle to be less than 360 degrees thus preventing the wires therein to be twisted and broken.
