Title: Pacemaker with vasovagal syncope detection
Inventor: MARKOWITZ H TOBY
IPC: A61N1/365
Filed: 1995-03-08
Granted: 2001-03-13
Abstract: Pacemaker with improved detection methods for occurrence of vasovagal syncop e episodes. Increased rate pacing followed by fallback to lower rate is a retained feature. The lower rate need not be rel ated to the increased pacing rate. One alternative detec ts stable or persistent rate below a threshold rate after a rapid rate drop through the t hreshold rate. Another alternative detects a "top rate" as a highest persistent rate and compares the difference between it and the rate that fol lows a rate drop through a "drop rate" or other threshol d level. Yet another alternative finds a persistent rate above a first threshold rate  before initiating the rate drop detection function. Onc e initiated, this embodiment preferably detects a rate drop from above said first thresho ld to below a second threshold rate, and also preferably  detects a stable rate below said second threshold rate. Adaptations to avoiding paci ng activation during sleep and combinations of the vario us embodiments are discussed.

Title: Multicylinder boxer crankshaft assembly
Inventor: BARSKI WOJCIECH GRZEGORZ
IPC: F16C3/06
Filed: 1997-01-24
Granted: 2000-04-11
Abstract: In typical internal combustion engines and compressors, etc., it is known to have a piston, moving in a cylinder, connecting rod and a crankshaft, as a crankshaft system.      The gas and inertia forces press the piston against the cylinder side wall and produce bending stresses in the connecting rod.    With increased speed the effect of inertia forces may exceed this of gas forces. The second harmonic inertia force may cause bigger stresses than its first harmonic. This puts heavy demand on all components, posing limitations to speed and power.      Balancing is also difficult.

Abstract: An isolator surge protector (ISP) is provided which blocks DC current and passes AC current and AC and DC fault currents. The ISP includes a main bypass path, including main bypass path switching devices, that is connected in parallel with a DC blocking capacitor.      Primary triggering of the main bypass path switching devices occurs when the voltage across the ISP exceeds a primary voltage trigger level. Repeated triggering of the bypass path switching devices, and high current discharge of the high voltage DC blocking capacitor through the bypass path, under abnormal steady state voltage conditions, is prevented by initiating a secondary triggering period following primary triggering of the bypass path switching devices. During the extended secondary triggering period, triggering of the bypass path switching devices occurs at a low secondary voltage trigger level. Primary triggering of the bypass path switching devices preferably also occurs when the AC current in the DC blocking capacitor exceeds a selected primary current trigger level, thereby protecting the DC blocking capacitor from damage due to excessive currents. Primary triggering due to high AC current levels in the DC blocking capacitor is also followed by a secondary triggering period during which triggering of the bypass path SCRs occurs at the low secondary voltage trigger level. The ISP preferably also provides a warning indication when primary triggering of the bypass path switching devices occurs.

Granted: 2008-09-09
Abstract: Midspan access to selected optical fibers which are encapsulated in an optical ribbon or tube is achieved by placing the desired span of the encapsulated fibers to be accessed between opposing abrasive layers and controllably urging at least one of the abrasive layers in the direction of the opposing abrasive layer to cause both abrasive layers to contact the encapsulant which covers the fibers. The amount of force applied to the at least one abrasive layer is limited by the structure of a resilient element which is coupled to the abrasive surface. Stress concentrators are created in the encapsulant and the encapsulant is removed from the span portion by relative movement of the encapsulated fibers and the abrasive layers. A minimum separation distance between the opposing abrasive layers can be defined, according to the thickness of the specific encapsulated fiber medium undergoing fiber separation, to avoid contact between the abrasive surfaces and the fibers within the medium. Access to the individual fibers is provided after the stress concentrators are formed in the encapsulant or encapsulant in the desired span portion has been substantially removed.
