Title: Rotor position encoder for an electrical machine.
Inventor: COPPER ANDREW JAMES
IPC: G01D5/245
Filed: 1997-06-11
Abstract: A rotor position encoder is provided for an electrical machine having a rotor and a stator, the encoder including a coded disc having teeth of widths that vary in a repeating sequence and being arranged to rotate with the rotor past a sensor which outputs a signal corresponding to the coded sequence. By comparing the coded signal with an internally generated signal the position of the rotor can be determined at a first resolution level. In addition, a counter is enabled as each tooth is sensed and provides a second output signal at a higher resolution level indicative of the rotor position between successive teeth. For a multi-phase machine, a value representative of the rotor position relative to each phase is combined with the value representative of the incremental position common to all phases.

Title: Stroke limiter for hydraulic actuator pistons in compression release engine brakes.
Inventor: CUSTER DENNIS R
IPC: F15B15/24
Filed: 1997-07-25
Abstract: A clip valve for limiting the stroke of an exhaust-valve operating hydraulic actuator piston (20) in a compression release engine brake has a plunger (60) which follows the actuator piston down until the motion of the plunger is stopped by a retaining ring (80) in a bore (72) in which the plunger reciprocates. When the plunger is thus stopped, an aperture (24) in the slave piston (20) is uncovered, thereby allowing pressurized hydraulic fluid to escape from the actuator piston cylinder (40) and preventing further downward motion of the actuator piston. The clip valve apparatus is constructed to facilitate assembly of the plunger and retaining ring in the bore, as well as to provide secure and fail-safe retention of those components in the bore. The parts of the clip valve are simplified and preferably also reduced in number as compared to the prior art.
Patent MX-9705652-A (MX)
Title: A device and process for generating and measuring the shape of an acoustic reflectance curve of an ear.
Inventor: COMBS JEROME T
IPC: G01H15/00
Filed: 1997-07-25
Abstract: A device or a process for analysis of acoustic reflectance of components of an ear involves directing, into the ear canal, acoustic waves covering a range of frequencies including resonance frequencies of ear components such as the tympanic membrane. Measurements are made without pressurizing the ear canal and contact between the device and the ear does not need to be air-tight. Accordingly, the patient experiences essentially no discomfort from use of the device. The device detects and combines the incident and reflected waves to produce what is called an acoustic reflectance curve. The shape of a region of the acoustic reflectance curve is electronically measured in order to obtain an indicator of ear condition which is substantially independent of a line of sight between a sound source and the tympanic membrane. This indicator is based on a mesurement of the resonance characteristic, or freedom of motion, of the tympanic membrane or other ear component being analyzed. One such measurement is the rate of change of the acoustic reflectance with respect to frequency. Since resonance typically causes a null to appear in the acoustic reflectance curve, this measurement of the rate of change is particularly informative if measured around the null. The rate of change measured around the null may be presented as an angle measurement, a gradient or slope measurement, a width measurement, or other form of measurement of the shape of the null. In one embodiment, the steepest slopes on either side of a null are used to define an angle, herein called a spectral gradient. Diagnosis of an ear pathology, such as abnormal pressure or presence of fluid in the middle ear or such as conductive hearing loss, may be based on this measure alone. Because of the rate of change of an acoustic reflectance measurement is relatively constant for a given ear, regardless of the quality of the line of sight to the tympanic membrane, the effect, if any, of user training on such measurements is significantly reduced. Accordingly, the process and device of the invention are useful in many kinds of diagnostic situations with respect to ear pathology, but particularly in those involving screening of the ears of young children for common pathologies such as otitis media, even by untrained personnel.

Patent MX-9803424-A (MX)
Title: Method for installing a wireless network.
Inventor: MELNIK GEORGE A
IPC: H04L12/28
Filed: 1998-04-30
Abstract: A method for installing a wireless network, which includes the steps of physically installing a plurality of nodes in respective different locations in a building, and using a wireless installation device to program a respective address into the nodes. The wireless installation device may also be used to program one or more default settings into the nodes, to verify operation of the nodes, and to dump information regarding the physical location and associated address of the nodes to a building computer. The wireless programming of the nodes is preferably accomplished using a software "handshaking" procedure which ensures that the address and default setting data is only loaded into the node currently being programmed, and not inadvertently into one or more other nearby nodes. In this connection, an iterative power reduction scheme can be utilized to prevent multiple nodes from being inadvertently assigned the same address.

Patent NL-6509350-A (NL)
IPC: B22F3/11
Filed: 1965-07-20
Abstract: A surface region of a body of titanium or a titanium -base alloy of similar anodic polarization properties is coated with a fine scale mixture of a relatively insoluble metal and a more easily soluble metal and the latter is subsequently dissolved out thus forming an electrode having a large surface area.  As described the insoluble metal is one of the Group VIII platinum group metals or an alloy consisting of such metals and the soluble metal is copper, silver, nickel or tin. The fine scale mixture may be formed by successively electro-plating with the insoluble and soluble metals and heating to cause them to interdiffuse e.g. by plating titanium with platinum from an alkaline bath containing sodium hexahydroxy platinate, optionally heating, e.g. at 780 DEG C., to bond the plating to the base, then electro-plating with copper and heating to 400 to 800 DEG C.  The soluble metal e.g. copper may then be removed by chemical etching in nitric acid or anodic etching in sulphuric acid.  The resulting electrode has a reduced over-voltage when used as anodes e.g. in the electrolysis of sodium chloride solution. Reference is made to effecting coating by dipping, chemical reduction, or vapour deposition, or pack treatment in metal powder, and to co-deposition of the insoluble and soluble metals prior to electro-plating the titanium may be etched in HCl and scrubbed with abrasive powder.
