Title: Multimedia capture and audit system for a video surveillance network
Inventor: ODLE JAMES A
IPC: G08B13/196
Filed: 1995-02-02
Abstract: A multimedia capture and audit system for a video surveillance network provides a tamper resistant and easily reviewable record of each transaction monitored.  The system stores a digital record of each physical transaction registered by an electronic device in a standard predefined database format and stores a separate mixed composite video signal containing both a visual record and digital record of each transaction.  The separately stored digital record and mixed composite video signal are correlated through the use of a unique system pointer.  In the preferred   embodiment, the unique system pointer identifies, at a minimum, the electronic device which registered the physical transaction and the date and time of the transaction.  Storage of both a mixed composite video signal and digital record makes it difficult to tamper with the transaction record while maintaining a record of each transaction in a digital format provides operators the ability to compile and analyze data for audit purposes. Use of the unique system pointer makes it easy to identify and view the portion of the mixed composite video signal which corresponds to any digital record that may be flagged as of interest in an audit.

Title: Method for producing hydrogen-carbon monoxide mixed gas, and apparatus thereof
Inventor: KISO FUMIHIKO
IPC: C10J3/02
Filed: 1996-08-30
Abstract: A method and apparatus for producing methyl alcohol with high efficiency and low cost involve producing an H2-CO mixture that is used for synthesizing methyl alcohol, using coal, natural gas, steam, and an oxidizing agent, such as oxygen, as raw materials.  At least one of the ratios of natural gas/coal, oxygen/coal, and steam/natural gas are controlled to generate the H2-CO mixture in which the ratio of H2/CO is equal to 2, which is suitable for synthesizing the methyl alcohol. In producing the H2-CO mixture, coal and oxygen are reacted to generate CO, CO2, H2O, H2, and heat, and the heat is utilized to react the natural gas and steam for generating the H2-CO mixture.  In comparison with conventional methods for producing methyl alcohol from natural gas, and by coal gasification, the conversion ratio from the raw material to methyl alcohol can be improved by about 10 - 15 %.

Title: Hydraulic inertial vibration isolator
Inventor: STAMPS FRANK B
IPC: F16F15/023
Filed: 1995-03-31
Abstract: A hydraulic inertial vibration isolator (1) is connected between a vibrating body (3) and an isolated body (5). The vibration isolator (1) comprises a cylinder (7) which includes two chambers (35, 37) and a piston (9) therebetween. The chambers (35, 37) are connected by a tuning passage (31) in which a solid tuning slug (33) is slidably disposed. The chambers (35, 37) and the tuning passage (31) are filled with liquid.  Bypass passages (57, 61) connecting the tuning passage (31) to the chambers (35, 37) allows file liquid pressure in the chambers (35, 37) to equalize when the amplitude of the tuning slug's oscillatory motion is sufficiently large, thereby limiting the tuning slug's amplitude. Dashpots (45, 47) axially disposed adjacent to either end of the tuning slug (33) act to damp excessive tuning slug motion and to bias the tuning slug (33) toward the center of the tuning passage (31). An electronic control system (69) is used to supply alternate current to magnetic coils (67) adjacent to the tuning slug (31), thereby matching the isolation frequency to the vibration frequency.

Title: Laser-assisted electrosurgery system
Inventor: TAYLOR KENNETH D
IPC: A61B17/00
Filed: 1995-07-10
Abstract: A laser and electrosurgical system (10) has a handpiece (12) with a proximal and distal end (13) and (14) from which laser radiation (17) and/or electrosurgical energy (18) is selectively or concurrently directed. The ends are along an axis; an electrode extends distally along the axis. Sources of laser and electrosurgical energy (18) are available and controlled. An initiation circuit (25) for the laser selectively delivers it before electrosurgery. Prior delivery to target tissue, the laser creates an ionized conductive pathway for electrosurgery. The combined concurrent application of laser and electrosurgery has a mechanism (27) to selectively distribute energy about the axis. A laser deflecting surface (28) or a beam deflector vibrate relative to the axis. A power switch (30) has levels for laser cut and ionization and/or a delay therebetween for electrosurgical coagulation. A wave guide (34) or an array thereof deliver radiation along the axis. A method has steps of directing selectively and concurrently laser and electrosurgery by aiming the axis, controlling laser and electrosurgical energy (18), delivering laser before electrosurgery, forming an ionized conductive pathway for the electrosurgery, distributing the laser about the axis in a predetermined pattern by deflecting the laser in a predetermined pattern generally along but slightly displaced from the axis to direct electrosurgical energy (18) in a predefined pattern on the patient's (11) target tissue. In another possible approach, there are additional steps of delivering the laser radition (17) as a beam and varying an ionized conductive pathway by refracting or diffracting the laser radiation (17) beam with the mechanism (27) having a beam pattern deflector.

Patent CA-2198709-A1 (CA)
Inventor: JARVINEN KARI
IPC: H04W88/02
Filed: 1995-09-19
Abstract: The invention relates to a method for detecting defective speech frames in a receiver of a speech communication system. A coded speech signal (200) consisting of speech frames conveying speech coding parameters is received through a transmission link. In the invention, the detection method (206) for defective speech frames is dependent on the quality of the transmission link. If the quality (210) of the transmission link is "poor", unusual parameter values of a speech signal in a speech frame are interpreted as transmission errors, and the speech frame is classified as defective. During a transmission link of "good" quality, all received parameter values possible for speech are accepted and forwarded to a speech decoder (203). In the latter mode of operation, the detection of defective speech frames is solely based on conventional error detection methods (205) employed in the receiver.
