Abstract: A tendon tensioning anchor (12) comprising a base member (30) having a tubular section (32) extending therefrom, a plas-tic encapsulation (14) in surface-to-surface contact with the exterior of the base member, and a heat shield (151) fastened within the plastic encapsulation adjacent an end of a tubular section extending outwardly from the base member. The plastic encapsula-tion opens at the end of this tubular section opposite the base member. The plastic encapsulation further comprises a tubular por-tion (22) formed at the side of the base member opposite the tubular section and extends outwardly perpendicular to the base member. The heat shield (151) is a rigid member having an outer diameter corresponding to the outer diameter of the tubular sec-tion. The heat shield has an interior surface formed therein for receiving a portion of a sealing cap (20). The present invention al-so includes an extension tubing (16) fitted to the end of the tubular portion of the plastic encapsulation. A seal (208) is fastened within the other end of the extension tubing so as to create a liquid-tight seal with a tendon (24) passing therethrough.

Title: Apparatus and method for sensing tampering of utility meter
Inventor: CARNEY MURRAY C
IPC: G01R11/24
Filed: 1993-07-22
Granted: 2001-04-10
Abstract: A device for detecting tampering of a utility meter includes sensors to detect a positional displacement of the meter and lose of power to the meter. On sensing a positional displacement of the meter, indicative of an attempt to remove the meter, a timer is activated to enable sensing a power loss to the meter. In response to detection of a power loss during the time period defined by the timer, an indication is stored in a nonvolatile memory of the tamper event. In response to loss of power with or without a detection of tampering, required parameters including utility consumption data are stored in nonvolatile memory. Remote access to and data retrieval from the nonvolatile memory and system are provided over telephone lines, power lines, or a radio frequency circuit.

Title: Method and apparatus for background control in an electrostatographic printing machine

IPC: G03G15/043
Filed: 1994-10-25
Granted: 1996-03-26
Abstract: A method and apparatus for determining the presence of image information in the lead edge of an input document by comparing the average difference between a plurality of instantaneous optical density measurements of a reference strip and the average optical density for the reference strip to the average difference between a plurality of instantaneous optical density measurements of a lead edge of an original input document and the average optical density for the lead edge of the original input document. Analysis of optical density measurements during scanning of the lead edge of an original input document is accomplished so that image information on the lead edge of an original input document is not misinterpreted as indicative of a dark background original input document. The method and apparatus provides novel control of bias voltages applied to subsystems in an electrostatographic printing apparatus in response to the presence or absence of image information in the lead edge of an input document so that both background development and the loss of image density for images on the lead edge of a document is minimized by setting the exposure lamp voltage, and/or the developer bias, charging potential, as well as other variable parameters to predetermined settings in response to the detection of image information in the original input document.

Parallèlement, on mesure le niveau de l'électrolyte HT dans la cuve à partir d'un point de cote de référence par enregistrement de la variation de potentiel entre le substrat cathodique et la sonde, dont la position est déterminée par un potentiomètre et dont le potentiel augmente brusquement lorsque l'extrémité inférieure de la sonde, ou pointerolle, entre en contact avec l'électrolyte.

Title: Write anywhere file-system layout
Inventor: HITZ DAVID
IPC: G06F16/10
Filed: 1995-12-21
Granted: 2004-05-25
Abstract: The present invention provides a method for keeping a file system in a consistent state and for creating read-only copies of a file system. Changes to the file system are tightly controlled. The file system progresses from one consistent state to another. The set of self-consistent blocks on disk that is rooted by the root anode is referred to as a consistency point. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the fsinfo block (2440) is updated by writing a new root anode for the anode file (1210) into it. Thus, as long as the root anode is not updated, the state of the file system represented on disk does not change. The present invention also creates snapshots (Figure 22) that are read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snap shots can be created for the same file system. Unlike prior art file systems that create a clone by duplicating the entire anode file and all of the indirect blocks, the present invention duplicates only the anode that describes the anode file. A multi-bit free-block map file (1630) is used to prevent data from being overwritten on disk.

Title: Electrosurgical hemostatic device with adaptive electrodes
Inventor: SCHULZE DALE R
IPC: A61B17/072
Filed: 1996-04-10
Granted: 2007-03-13
Abstract: An improved electrosurgical device having an end effector capable of receiving electrosurgical energy therein. The end effector comprises first and second opposing interfacing surfaces. The interfacing surfaces are capable of engaging tissue therebetween. There is provided a first electrode of a first electrical potential and a second electrode being insulated from the first electrode and having a second electrical potential that is different from the first electrical potential. The first and second electrodes are arranged to receive the electrosurgical energy therein. The opposing interfacing surfaces are electrically insulated and the first electrode is located on the first interfacing surface and the second electrode is located on one of the first and second interfacing surfaces. The improvement resides in that the first electrode is a spring electrode that is flexible so that it is moveable towards and away from the first electrode and is biased towards the second electrode. The result is that this enables the distance between the electrodes to be continuously adaptable to different tissue impedances due to different thicknesses and compressibilities of the engaged tissue. In another aspect the invention provides an electrosurgical kit comprising the electrosurgical device and at least two interchangeable cartridges, which cartridges are insertable into the end effector to form at least a portion of a first interfacing surface.
