Granted: 1995-10-31
Abstract: An apparatus for detecting loosening of an implant imbedded in a bone of a limb of a patient, includes a vibrator is pressed into engagement with the limb to impart vibratory motion to the bone.  The vibrator is controlled to cause the vibratory motion to have a predetermined recurring pattern.  A pickup device is pressed into engagement with the limb spaced from the vibrator over the same bone near the implant, for detecting the vibratory motion transmitted through the bone implant composite to generate an output signal.  Implant loosening is determined when the recurring pattern of the output signal transmitted through the bone implant composite demonstrates sustained superimposition on the oscilloscope and/or significant secondary harmonics on the spectrum analyzer.

Title: Surface condition measurement apparatus
Inventor: MARUI TOMOHIRO
IPC: G01J5/00
Filed: 1992-11-17
Granted: 1997-09-23
Abstract: Radiated light with a specified wavelength from a material is detected and a first parameter corresponding to the emissivity ratio is obtained from the detection signal.          Since the emissivity takes on different values according to the condition of the surface of the material, the first parameter changes depending on the surface condition of the material.  There is a correlation between a physical value indicating a condition of the material surface and the first parameter.  The correlation remains equivalent even if a second parameter corresponding to the physical value is used instead of the physical value itself (for example, an optical physical value such as reflectivity and absorptivity, the thickness of a film formed on the material surface, the surface roughness, and the degree of galvannealing).  As an example of the parameter corresponding to the physical value, there is the logarithmic ratio between emissivities (ln .epsilon. a/ln .epsilon. b) corresponding to the temperature in the vicinity of the surface.  Therefore, a second parameter can be obtained on the basis of the correlation and a physical value can be obtained.  When the emissivity or logarithmic emissivity ratio is used as the second parameter, the temperature in the vicinity of the material surface can be obtained from the second parameter and the detection signal.

Title: Method and system for modem command processing during data transfer
Inventor: BRIGIDA DAVID JOSEPH
IPC: G06F13/00
Filed: 1993-01-18
Granted: 1997-05-13
Abstract: A method and system are disclosed for permitting selected command sequences to be processed by a modem during data transfer operations. A preselected escape character is designated and inserted into a data stream to be applied to a modem in order to identify a selected command sequence which follows. A termination character is inserted into the data stream following the selected command sequence. Upon detection of the preselected escape character, the selected command sequence is coupled to a command processor within the modem and processed. In applications in which the modem is coupled between a data processing system and a cellular telephone communication channel, the selected command sequence may be utilized to transmit communication channel parameter status queries to a cellular telephone associated with the modem. In this manner, the Received Signal Strength Indicator (RSSI), bit error rate, or other indications of communication channel status may be queried. An identical technique may be utilized to transmit a response to each such query to the data processing system, permitting real time display of cellular communication channel status information during data transfer.

Granted: 1998-06-30
Abstract: In a case, a delivery reel for supplying a coating film transfer tape and a take-up reel for recovering the coating film transfer tape are rotatably provided, a pointed head for transferring the coating film is projectingly provided at an end of the case.  The delivery reel is constructed such that a delivery cylinder is rotatably fitted over the outer periphery of a boss portion of a driving gear wheel through an elastomeric frictional member and the take-up reel is constructed such that a follower gear wheel being in  meshing engagement with the driving gear wheel is provided over the outer periphery of a take-up cylinder, whereby an end of a coating film transfer tape wound around the delivery cylinder is delivered from the delivery cylinder and reversed at a pointed portion of the head, and wound around the take-up cylinder. When a delivery speed of the coating film transfer tape and a take-up speed go out of balance with the progress of operation, the delivery cylinder is idly rotated with respect to the boss portion of the driving gear wheel through the frictional member, whereby the above-described both speeds are brought into synchronism with each other.  Owing to this, the coating film transfer tape can smoothly run at all times.
