Publication number: 20180225944Abstract: A system for monitoring multiple patients within a facility comprises a plurality of monitoring apparatuses, a central communication hub, and a plurality of notification devices. The monitoring apparatuses generate data relating to the status of patients, and send the data to the communication hub. The data may include an alarm signal. In a variant, the monitoring apparatuses do not generate alarm signals. Rather the communication hub processes the data and generates alarms if needed. Alarms are sent by the communication hub to the notification devices to inform employees of the facility of the source of the alarm.Type: ApplicationFiled: April 9, 2018Publication date: August 9, 2018Applicant: J. Brasch Co., LLCInventors: John Joseph Brasch, Gordon Smith, JR., James Leacock

Patent number: 6069664Abstract: The present invention is embodied in an apparatus and method for converting a progressive video signal to an interlaced video signal from which the progressive video signal may be recovered. The invention is further embodied in an apparatus and method for converting such an interlaced video signal to a progressive video signal. A progressive-to-interlaced video converter includes a progressive video preprocessor and a converter. The progressive video preprocessor replaces at least one scan line in a video frame by its preceding or succeeding scan line. Alternatively, the preprocessor may assign a predetermined value to one or multiple scan lines at appropriate position(s) in a frame. In either scenario, each frame will carry at least one redundant scan line. The frame modification information will be encoded to an ancillary data section of a digital video stream.Type: GrantFiled: June 4, 1997Date of Patent: May 30, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Daniel Qiang Zhu, Kaarlo Juhani Hamalainen, Thomas James Leacock, Kevin John Stec

Patent number: 5841413Abstract: A plasma display device employs a minimum moving pixel distortion (MPD) set of codewords for reducing visually perceived artifacts viewed on a plasma display panel (PDP). The plasma display device includes a minimum MPD mapping process, which maps by, for example, a ROM look-up table, received pixel intensity values into intensity levels corresponding to selected ones of the set of codewords. By increasing the number of subfields (or rounding the least significant bits (LSBs) of the intensity pixels), redundant codewords that express pixel intensities can be generated based on the sustain pulse vector with predetermined constraints. An optimal set of codewords can be determined though (1) a random search; (2) an exhaustive search; (3) dynamic programming or (4) a genetic algorithm based search which minimizes the MPD distance. The mapped codewords are stored in a ROM lookup table as display data by a plasma display controller.Type: GrantFiled: June 13, 1997Date of Patent: November 24, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Daniel Qiang Zhu, Thomas James Leacock

Patent number: 5819035Abstract: A video signal encoding/decoding system reduces ringing noise by using a post-filter which performs anisotropic diffusion on decoded data. The exemplary system uses an encoding/decoding technique such as that developed by the Moving Picture Experts Group (MPEG). The post-filter processes individual blocks of pixels, assigning an individual edge significance threshold to each block. Noise removal occurs if the edge strength is below the threshold and is inhibited if the edge strength is above the threshold.Type: GrantFiled: October 20, 1995Date of Patent: October 6, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Patrick William Devaney, Daniel Chandran Gnanaprakasam, Thomas James Leacock

Patent number: 4263448Abstract: An oxidizable hydrocarbon is oxidized in a reaction zone at elevated temperature in the presence of a liquid reaction medium by introducing the hydrocarbon and a feed stream containing molecular oxygen to the reaction zone under conditions sufficient to oxidize at least a portion of the hydrocarbon; withdrawing at least a portion of the liquid reaction medium from the reaction zone; passing at least a portion of the withdrawn liquid reaction medium to an oxygen injection zone located external to the reaction zone; contacting the liquid in said oxygen-injection zone with a gas stream containing molecular oxygen under conditions sufficient to form a two-phase gas/liquid mixture; and passing said two-phase gas/liquid mixture to the reaction zone as the feed of molecular oxygen thereto.Type: GrantFiled: March 30, 1979Date of Patent: April 21, 1981Assignee: Halcon Research and Development Corp.Inventor: James Leacock

Patent number: 4252748Abstract: Acetone produced as a by-product in the reaction of methyl acetate with carbon monoxide and hydrogen in the presence of a Group VIII noble metal catalyst and methyl iodide is recovered from the reaction mixture by supplying acetone to provide an acetone to methyl iodide molar ratio of at least 1:10 and distilling the mixture comprising methyl iodide, acetone and methyl acetate to separate substantially all of the methyl iodide and the supplied acetone and some of the methyl acetate from the remaining acetone and methyl acetate and thereafter separating the acetone from the methyl acetate.Type: GrantFiled: December 29, 1978Date of Patent: February 24, 1981Assignee: Halcon Research and Development CorporationInventors: Robert Hoch, James Leacock, Chee-Gen Wan

Patent number: 4147721Abstract: In an oxidation process for converting methacrolein to methacrylic acid, methacrylic acid is recovered by cooling and condensing the effluent from the oxidation, followed by azeotropic distillation of the condensate with a suitable solvent, such as methyl n-propyl ketone. The condensed effluent contains methacrylic acid and water as the major components along with by-product acetic acid, a minor amount of unreacted methacrolein and impurities. Substantially dry crude methacrylic acid is separated as a bottom product from the azeotropic distillation and an azeotrope of water and the solvent is taken overhead and condensed. After condensation, solvent-rich and water-rich phases form and are separated. The solvent-rich phase is returned to the distillation column as a reflux, while the water-rich phase is sent to a stripping column for recovery of residual solvent. Water is withdrawn from the bottom of the stripping column and recycled or discarded, as desired.Type: GrantFiled: April 6, 1978Date of Patent: April 3, 1979Assignee: Halcon Research and Development CorporationInventor: James Leacock
