Patent number: 6188256Abstract: A reset device is disclosed which is part of a micro-controller formed on an integrated circuit. The reset device has a counter which outputs a count enable signal after counting a predetermined number of counts. In response to an input reset signal, an input device of the reset device provides a start signal to the counter for initiating count-down thereof. An output device outputs an output reset signal in response to the start signal and the count enable signal. The start signal is inhibited by a control signal, which is provided from a control device in response to an external reset signal received at an input pin of the micro-controller. The input device includes an AND gate which receives the input reset signal, an inverted delayed version of the input reset signal, and the disable signal. The reset device further includes an OR gate which receives the start signal and the count enable signal to provide an input signal to the output device for generation of the output reset signal.Type: GrantFiled: December 7, 1998Date of Patent: February 13, 2001Assignee: Philips Electronics North America CorporationInventors: Neil Edward Birns, Jie Zheng, William Jay Slivkoff

Patent number: 6185363Abstract: A video indexing system analyzes contents of source video and develops a visual table of contents using selected images. The source video is analyzed to detect video cuts from one scene to another, and static scenes. Keyframes are selected for each significant scene. A keyframe filtering process filters out less desired frames including, for example, unicolor frames, or those frames having a same object as a primary focus or one primary focuses. A visual index is created from those frames remaining after the keyframe filtering and stored for retrieval. The visual index may be retrieved by a user who may then display the visual index on a display. The user may select one of the frames displayed in the visual index and the source video may be manually (by the user) or automatically advanced to that frame of the source video. Additionally, a user may print the visual index.Type: GrantFiled: November 8, 1999Date of Patent: February 6, 2001Assignee: Philips Electronics North America CorporationInventors: Nevenka Dimitrova, Thomas McGee, Jan Hermanus Elenbaas

Patent number: 6173037Abstract: An X-ray fluorescent method for performing measurements on a thin layer provided on a substrate, notably a silicon substrate provided with a layer of tungsten silicide (WSix). The layer thickness and the concentration of the chemical elements in the layer can be determined in known manner by measurement of the intensity of a hard and a soft X-ray line in the fluorescent radiation. In conformity with the invention, the reliability and/or the accuracy of this determination can be established by measurement of the intensity of a third X-ray line, preferably being a line whose wavelength lies between that of the first two lines. Using a minimization procedure (least squares method applied to &khgr;2), the optimum values of c and d are determined. The accuracy of the determination can be established by variation of the optimum value of &khgr;2.Type: GrantFiled: July 13, 1999Date of Patent: January 9, 2001Assignee: U.S. Philips CorporationInventor: Peter N.

Patent number: 6154160Abstract: A circuit checks the value and the existence of an external load of a digital-to-analog current converter. A first comparator compares a digital word to be converted, with a comparison data word. The output signal of the first converter indicates during which periods the digital data word is greater and during which periods it is smaller than the comparison data word. A second comparator compares the voltage at the output of the converter with a reference voltage. The output signal of the second converter indicates during which periods the output voltage is greater and during which periods it is smaller than the reference voltage. A comparison circuit checks the existence and the value of the output load by comparing the time periods indicated by the output signals of the two converters. Thus, a conclusion about the existence and the value of the output load is possible at any time.Type: GrantFiled: February 19, 1999Date of Patent: November 28, 2000Assignee: U.S. Philips CorporationInventors: Robert Meyer, Othmar Pfarrkircher

Patent number: 6148669Abstract: An acceleration sensor (100) includes a spherical chamber (104) accommodating a spherical member (106) made from an inductance influencing material. The member is inductively coupled to one or more coils (110) outside the chamber. A force on the sensor pulls the member to a certain position in the chamber, which position corresponds to the direction of the force. The position is measured on the basis of the self induction of the coil or coils. In a steady state, the position of the member is representative of the orientation of the sensor with respect to the field of gravity.Type: GrantFiled: October 23, 1998Date of Patent: November 21, 2000Assignee: U.S. Philips CorporationInventor: Wouter Roest

Patent number: 6148003Abstract: The invention relates to an information distribution system with a plurality of stations (100, 102, 104) and at least one shared resource (120, 122), such as an audio channel. Access to a shared resource is managed in a distributed manner. Each station comprises a controller 154. If a station requires a shared resource, the controller 154 of the station checks resource status information stored in a local memory 156 to determine whether the shared resource is available. If the resource is available, the controller 154 selects the available shared resource and uses communication means 150 to send a status message informing other ones of the stations that the station uses the selected resource. Next, the controller 154 uses access means 152, such as an audio selector, to access the selected resource. Upon receiving the status message, controllers 154 of the other stations update the resource status information stored in the local memory 156 according to a received status message.Type: GrantFiled: September 15, 1997Date of Patent: November 14, 2000Assignee: U.S. Philips CorporationInventor: Erik J.

Patent number: 6122751Abstract: A pipelined circuit contains a cascade of stages, each with an intial register followed by a combinatorial logic circuit. The registers are clocked. At the beginning of each clock period, data in the initial register is updated. After that, during the clock period, data propagates from the initial register, along a path through the combinatorial logic circuits, to the initial register in the next stage where it is stored at the beginning of the next cycle. In the path there are several other registers, in which the data is stored at intermdiate phases of the clock cycle, while the data is kept in the initial register. Thus differences in propagation delay along different branches of the path are eliminated without increasing the number of clock cycles needed to pass data through the pipelined circuit. This reduces the number glitches which consume energy without affecting the function of the circuit.Type: GrantFiled: December 9, 1996Date of Patent: September 19, 2000Assignee: U.S. Philips CorporationInventors: Mark A. E. Janssens, Stefaan M. M. Note

Patent number: 6122626Abstract: The invention relates to a method of searching a plurality of values in an ordered list. Given a data set consisting of data items. With each data item one or more attribute values are associated, which are all stored in an ordered list. Efficiently retrieving the data items associated with a particular set of entered values is accomplished by using the list. The list (partially) resides in slow secondary memory and, and a subset thereof, the sparse index, resides in primary memory. Both indexes preserve some natural ordering of the values. The invention proposes to look up the particular set of entered values in the list in one combined operation, rather than individually. The accumulated retrieval time is substantially reduced as a result.Type: GrantFiled: March 13, 1998Date of Patent: September 19, 2000Assignee: U.S. Philips CorporationInventor: Ewout Brandsma
