Title: Apparatus for writing and/or reading information in/from a disc shaped record carrier
Inventor: MCGEE PHILIP J L
IPC: G11B7/09
Filed: 1987-11-12
Granted: 1992-09-29
Abstract: ABSTRACT: Apparatus for writing and/or reading information in/from a disc-shaped record carrier.     The apparatus comprises a light source (7) for producing a light beam, an objective system (8) for focussing the light beam, first detection means (13, 48) for generating a first control signal (S1) which has a value which varies substantially proportionally to the radial distance of the light spot relative to the track over a control range of p/4, p being the track pitch, and radial positioning means (47) for. controlling the radial position of the light spot (P) on the track (Fig. 1) under the influence of said first control signal. The detection means (13, 48) comprise correction means (48) for extending the substantially proportional control range to a value larger than p/4. The detection means (13, 48) derive the first control signal (S1) from the radial error signal (RE) (Fig. 4). Proportional radial positioning control can then be effected in such a way that even for excursions of the light spot up to a maximum of 3p/4 the light spot can still be returned to the track. The resulting position control is far more immune to mechanical shocks (Fig. 3).

Title: Apparatus and methods for improving uniformity measurements
Inventor: BEEBE JAMES C
IPC: G01M17/02
Filed: 1988-05-17
Granted: 1993-10-05
Abstract: APPARATUS AND METHODS FOR IMPROVING UNIFORMITY MEASUREMENTS Abstract of the Disclosure Apparatus and methods for use in measuring the uniformity of a body such as a tire, wheel or the like wherein a waveform related to the uniformity of the body is digitally sampled to acquire a series of data samples, each of which is correlated with a respective physical location on the body.  According to a first aspect of the invention, a non-repetitive error component of the waveform is corrected for by sampling the same location on the body at two differ-ent times and determining the difference between the corresponding data samples.  A part of the total difference is allocated to each of the data samples in the series according to a predetermined mathematical function which at least approximately describes the non-repetitive component of the waveform.  The part of the difference allocated to each sample is then subtracted from it to obtain a corrected series of data sample.  According to a second aspect of the invention, the maximum, minimum and/or peak-to-peak values of the waveform are more accurately determined by relating selected extreme data samples and one or more data samples adjacent thereto to a polynomial function of at least second order.  The function is then evaluated at the location where its first deriva-tive equals zero to determine a more accurate and repeatable approximation of a maximum, minimum or peak-to-peak value of the waveform.  According to yet another aspect of the present invention the first and second aspects above are practiced in conjunction with one another.

Title: Tooth-cleaning device and method
Inventor: KLINKHAMMER RONALD WILLIAM
IPC: A61C15/00
Filed: 1989-01-17
Granted: 1996-08-13
Abstract: The device and method employ a pair of spaced jaws which have a tooth cleaning implement connected there-with, in the gap therebetween. In use, the jaws are straddled about a row of teeth, transverse thereof, and translated along the row opposite the inside and outside faces of the teeth. Various features enable the user to locate and "steer" the device, even when the jaws and implement are out-of-sight to him. Other features enable the user to count on the device itself to provide the "dynamics" with which we commonly use a conventional "tooth brush" when we manipulate it in our mouths from a point thereoutside. Still others enable the user to program or predetermine the "grip" of the device, transverse of the row, and to do so, moreover, in the context of having an interchangeable or replaceable tooth cleaning implement thereon which is adjustable in "grip" each time a new implement is substituted for an old. Other features enable the user to clean both gums and teeth alike, as well as to dis-lodge debris from any pockets at the gum line, and to clean the interstices between pairs of teeth. Still others enable him to flush away debris which is generated by the device during the various tooth cleaning operations. The various features include, among others, a taco shell-like cartridge unit which is insertable in the gap between the jaws to serve as a tooth cleaning implement, and a module for forming such a cartridge. Initially, the module has a bat-like, spread wing configuration, but it is sufficiently flexible and/or pliable to be folded into the generally U-shaped configuration of a cartridge unit. The various features also include certain bristle which are used in certain tooth brushing heads of the device .

Granted: 1994-05-03
Abstract: ABSTRACT     A meat doneness tester is disclosed.  The invention uses the known principle that the doneness of the meat is directly proportional to the firmness of the meat, i.e. the more the meat is cooked the firmer it becomes.  The invention includes a body member, the lowermost portion(s) of the body member being co-planar, with the plane constituting a reference plane for positioning against the surface of the meat.  A probe is attached to the body member for up and down movement towards and away from the body member beneath the body member.  Spring means bias the probe downwardly, i.e. away from said body member.  Indicator means are provided for indicating the displacement of the probe member from the reference plane.  In the preferred embodiment, the probe, spring means and indicator means are provided in the form of a single element, namely a spring steel strip.  The strip is fastened to the body, and a probe portion is produced by forming the strip into a downwardly-projecting V-shape.  The free end of the strip constitutes an indicator, which points to a scale inscribed on the body member.
