Abstract:
A system and method for automatically updating a digital certificate prompts a user of a client computer to update a current digital certificate if a period of validity of the current digital certificate elapses or is about to elapse, and creates a new digital certificate if the current digital certificate needs to be updated. The system and method further deletes the current digital certificate, and loads the new digital certificate into a storage system of the client computer.
Abstract:
Identification of transmitters for signals received by a terminal To determine the transmitter of a given received signal, a list of candidate transmitters that may have transmitted that signal is determined A coverage zone to use for the received signal is also determined This coverage zone is the area where the terminal may receive the signal being identified. The predicted power for each candidate transmitter is then determined, e.g., using a path loss prediction model and the coverage zone. The predicted powers for the candidate transmitters are compared (directly or relatively) against the measured power of the received signal. The candidate transmitter with (direct/relative) predicted power closest to the (direct/relative) measured power is deemed as the one that transmitted the signal. Propagation delays may also be predicted and used for transmitter identification. The identified transmitters may be used to determine a position estimate for the terminal
Abstract:
A dichroic mirror includes a substrate, a first film stack, and a second film stack. The first film stack is deposed on the substrate and has a structure represented by a first formula: (2HL)n. The second film stack is deposed on the first film stack and has a structure represented by a second formula: (0.325H0.65L0.325H)m. ‘2HL’ and ‘0.325H0.65L0.325H’ respectively represent a double-layer sub-structure of the first film stack and a sandwiched sub-structure of the second film stack, and ‘n’ and ‘m’, which are integers, respectively represent the number of repetitions of the double-layer sub-structures and sandwiched sub-structures ‘H’ and ‘L’ respectively represent a high refractive index layer and a low refractive index layer, both of which have a height equal to ¼ of the reference wavelength of the dichroic mirror, and ‘2’, ‘0.325’ and ‘0.65’ are height coefficients.
Abstract:
An acoustic camera comprises a first sound pick-up device, a second sound pick-up device, and a switch. The switch is respectively connected to the first sound pick-up device and the second pick-up device and used to select the first sound pick-up device or the second sound pick-up device to reconstruct the sound field of the sound source of a detected object. The first sound pick-up device has a first microphone array, and the first microphone array is a near-field uniform microphone array. The second sound pick-up device has a second microphone array, and the second microphone array is a far-field non-uniform microphone array.

A capacitor includes the first electrode comprising the first conductive lines and vias, where the first conductive lines on the same layer are parallel to each other and connected to the first periphery conductive line, and the first conductor lines aligned in adjacent layers are coupled to each other by the vias; the second electrode aligned opposite to the first electrode comprising the second conductive lines and vias, where the second conductive lines on the same layer are parallel to each other and connected to the second periphery conductive line, and the second conductor lines aligned in adjacent layers are coupled to each other by the vias; and oxide layers formed between the first electrode and the second electrode, where the vias have rectangular (slot) shape on a layout. In one embodiment, the conductive lines and vias are metal, e.g. copper, aluminum, or tungsten. The vias can have various sizes.
Abstract:
The present invention relates to improved metal-oxide-semiconductor field effect transistor (MOSFET) devices with stress-inducing structures located at the source and drain (S/D) regions. Specifically, each MOSFET comprises source and drain regions located in a semiconductor substrate. Such source and drain regions comprise recesses with one or more sidewall surfaces that are slanted in relation to an upper surface of the semiconductor substrate. A stress-inducing dielectric layer is located over the slanted sidewall surfaces of the recesses at the source and drain regions. Such MOSFETs can be readily formed by crystallographic etching of the semiconductor substrate to form the recesses with the slanted sidewall surfaces, followed by deposition of a stress-inducing dielectric layer thereover.
Abstract:
A platen for use in printing on an object, wherein the platen has an adjustable area of a working surface on which to place the object. The platen surface includes a plurality of elements, wherein each element includes a flat surface that can be positioned at a working level at which the object is to be placed, and wherein an operator can insert or remove each element and thereby the corresponding flat surface of that element from the working level as required in order to provide a desired area of the working surface. In one embodiment, the platen includes a base plate and a plurality of elements which can be positioned on the base plate or removed to form a desired configuration of the working surface.
Abstract:
Apparatus is provided for mounting a pellicle to a photomask. A chamber has at least one port for filling the chamber with extreme clean dry air (XCDA) or an inert gas. A pellicle mounter is provided within the chamber. A vacuum ultra violet (VUV) light source is provided for irradiating a mask held by the pellicle mounter while the chamber is filled with the XCDA or inert gas. The mask is irradiated with the VUV light in an atmosphere of the XCDA or inert gas, and the pellicle is mounted to the mask while the mask is in the atmosphere of the XCDA or inert gas and exposed to the VUV light.
Abstract:
A game device includes a processor, a display device having a screen displaying a plurality of enemy vessel images, an invisible vessel image and a target-finding frame, and a joystick device. The enemy vessel images and the invisible vessel image are moving across the screen. The invisible vessel image is concealed in the screen. The joystick device controls movement of the target-finding frame in the screen. The processor is capable of transforming the invisible vessel image into a visible vessel image when the target-finding frame is moved to overlap the invisible vessel image. In case the enemy vessel images and the invisible vessel image are attacked, the processor executes in such a manner to blow the enemy vessel images and the invisible vessel image off the screen.
