A system is disclosed for using camera attitude sensors with a camera. A camera assembly includes a tripod base, a tripod head interface mounted on the tripod base, a tripod head mounted on the tripod head interface and a camera mounted on the tripod head. The tripod head enables the camera to pan and tilt. The system also includes a first optical encoder for detecting the amount that the camera has been panned and a second optical encoder for detecting the amount that the camera has been tilted. Two inclinometers are mounted on the tripod head interface to measure attitude of the tripod head. Two gyroscopes (“gyros”) are mounted on the camera assembly. Data from the encoders, gyros and inclinometers are packaged and sent to graphics production equipment to be used for enhancing video captured by the camera.

A screwdriver for driving collated screws including a slide body coupled to a housing for reciprocal displacement in a cycle including a retraction stroke and an extension stroke. A lever pivotably mounted to the slide body carries at one end a cam pin received in a cam slot in the housing with the other end of the lever advancing successive screws in the screwstrip, the cam slot having first and second camming surfaces for selective engagement by the cam pin to vary the relative positionning of the lever to be different for the same position if the slide body in the housing in the retraction strokes than in the extension stroke.

A system and method for performing data transfers within a computer system is provided. The system includes a controller configured to dynamically adjust the interleave of the communications required to perform a series of data transfer operations to maximize utilization of the channel over which the communications are to be performed. The controller is able to vary the time interval between the transmission of control information that requests a data transfer and the performance of the data transfer by signaling the beginning of the data transfer with a strobe signal sent separate from the control information. The controller is able to defer the determination of how much data will be transferred in the operation by initiating the termination of a data transfer with a termination signal. The method provides a technique for distinguishing between identical control signals that are carried on the same line. The system includes a memory device with control circuitry that allows no more than one memory bank powered by any given power supply line to perform sense or precharge operations.

A locked loop circuit having a clock hold function. The locked loop circuit includes a select circuit, phase mixing circuit, hold signal generator and latch circuit. The select circuit selects one of a plurality of phase values in response to a select signal, and the phase mixing circuit generates a first clock signal having a phase angle according to the selected phase value. The hold signal generator asserts a hold signal in response to a transition of the select signal, and the latch circuit latches the state of the first clock signal in response to assertion of the hold signal.

A secure agent system for communicating with a secure remote access system is disclosed. The agent system is suitable for execution on a base device which is configured to be coupled to the internet. The agent system initiates data communication with the remote access system by sending requests and receiving replies from the remote access system. The replies may include requests to retrieve, store, update, and/or delete data associated with the base device, which the agent system carries out. The agent system further provides reply data to such requests to the remote access system.

An output driver circuit and current control technique to facilitate high-speed buses with low noise is used to interface with high-speed dynamic RAMs (DRAMs). The architecture includes the following components: an input isolation block (120), an analog voltage divider (104), an input comparator (125), a sampling latch (130), a current control counter (115), and a bitwise output driver (output driver A 107 and output driver B 111).
摘要:
A device, a system, a method and a computer readable medium allowing a user to efficiently and easily add/remove or pair a processing device to a short distance wireless network is provided according to embodiments of the present invention. A user enters a PIN into a device. The device is then automatically paired to another device without any further user intervention to form a short distance wireless network in an embodiment of the present invention. A third party such as a manufacturer, reseller or telecommunication provider enables a processing device to be added to the short distance wireless network by generating a pairing message over the Internet or a SMS in an embodiment of the present invention. A user is able to know when a PIN code is invalid by a device performing error detection in another embodiment of the present invention. In still another embodiment of the present invention, the device also stores an error correction software component for correcting an erroneously inputted PIN.
