Title: Pull ring locking mechanism
Inventor: DICKIE ROBERT GERALD
IPC: H01R13/633
Filed: 1991-09-11
Granted: 2000-07-18
Abstract: A pivotable pull ring is permanently attached to a low profile electrical plug (11) by fashioning a locking stub (29, 30) at the attaching ends of the pull ring (12). Matching lack stub cavities (33) in the electrical plug have "one-way" locking tabs (34) which accept the locking stubs into the locking cavity during assembly, but which block the removal of the locking stub from the locking stub cavity once the locking stub is assembled into the locking stub cavity..The locking tab has a gentle ramp (35) on the outside, to facilitate displacement of the locking tab to allow entry of the locking stub during assembly, but has an abrupt shoulder (36) on the inside to prevent displacement of the locking tab after assembly.

Title: Computer controlled smart phacoemulsification method and apparatus
Inventor: COSTIN JOHN A
IPC: A61F9/007
Filed: 1992-01-02
Granted: 1999-05-11
Abstract: A method and apparatus for operating on the human eye detects changes in load, m ore specifically, mechanical impedance, of the transducer (300) and controls aspiration based on the load cha nges. A change from a lower load to a higher load indicates that harder tissue is being encountered and accordingly causes aspirat ion amount to increase. Conversely, a change from a higher load to a lower load indicates that aspiration amount should be quickly decreased since the tissue which is being encountered is softer. One way to detect the impedance is by a sensor (1008), e. g., a piezoelectric element coupled to the operating needle detecting the movement thereof.

Title: Suction dredger
Inventor: RINKER KARL
IPC: E02F3/94
Filed: 1994-02-25
Granted: 2000-08-22
Abstract: The invention relates to a dredger for the planned taking up of suction material, particularly for removing soil from underground pipes. The dredger has a pneumatic elephant trunk for taking up the suction material and which issues into a storage tank for the sucked up material and to which is connected an exhaust fan. In the storage tank the section material is separated from the suction air flag and is subsequently passed through a filter means positioned between the elephant trunk opening and the exhaust fan. In order to ensure a good separation on the part of the filter means for a long period of time, said filter means is formed by a coarse filter and a fine filter connected to the latter. The coarse filter is formed by a labyrinth or cascade-like flow channel, which is bounded by reciprocally displaced partitions and whose flaw cross-section increases in the flow direction. On the tank bottom can be provided a conveying means by means of which the suction material separated from the air flow can be removed continuously or at intervals from the storage tank.

Filed: 1993-03-29
Granted: 1998-07-28
Abstract: A layered coder includes a lower resolution predictive encoder (102) and a higher resolution encoder (402) providing coded low and high resolution signals at lines (110) and (218) respectively. The prediction error of the lower resolution predictive encoder (102) is provided as a prediction error estimate to the higher resolution encoder (402), the prediction error estimate being subtracted from the prediction error generated in the higher resolution predictive encoder (402) by the subtractor (210). This difference from the subtractor (404) is coded by the coder (212) whose output is made available on the line (218). The prediction error estimate from the up sampler (130) is added to the output from the decoder (220) by an adder (406) in order to complete the predictive loop of the higher resolution predictive encoder (402). The prediction error estimate can also be subtracted from the prediction error of the higher resolution predictive encoder in the transform domain. The layered coder makes available both higher and lower resolution coded signals, with good coding efficiency as the coding information obtained from the lower resolution encoder (102) is used in the coding carried out by the higher resolution predictive encoder (402).

Title: Method for recognizing handwritten input
Inventor: SEYBOLD JOHN L C
IPC: G06V30/10
Filed: 1995-05-08
Granted: 1999-12-14
Abstract: The present invention determines whether two discrete continuous segments of handwritten input S1 (210) and S2 (220) form part of the same handwritten input or are part of more than one, separate handwritten inputs. The present method calculates one or more substantially parallel distance (260) disposed substantially parallel to the writing access (230) and compares these distances to one or more predefined thresholds. The predefined thresholds specify minimum distance measures which must be exceed by the substantially parallel distances (260) for the discrete continuous segments (210, 220) to be judged as belonging to separate segments of handwritten input.
