Abstract: An inspection apparatus for viewing both sides of a plurality of coins including a three-dimensional enclosure with a top, a bottom and a plurality of sides in combination defining a hollow interior. A lens is secured within an aperture in the top and provides for magnified viewing of an interior location of the enclosure. A coin supply is secured to the enclosure and is adapted to hold a plurality of coins. The coins are advanced in succession from a holding position to an inspection position for viewing through the lens. A pair of planar shaped reflectors are secured within the enclosure interior and arranged in opposing and angularly extending fashion relative to the lens and the selected coin to be inspected and so as to facilitate a clearer viewing of the selected coin.    Following inspection, the coin is ejected and a further coin is transferred from the holding position to the inspection position.

Title: Optical layer quasi-centralized restoration
Inventor: DOVERSPIKE ROBERT DUNCAN
IPC: H04L12/56
Filed: 1999-02-17
Granted: 2002-10-22
Abstract: A wavelength-switching, mesh-based restoration method among a network of optical cross-connects (OXCs) (10) is disclosed. The method is defined as "quasi-centralized" in that the network is first partitioned into a plurality of subnetworks (30,40), then a single "restoration controller" (22) is defined for each separate subnetwork. The subnetwork partitioning is defined as being either "minimally overlapping", meaning that the OXCs are "clustered" in their network topology, with only a few links required to join the various, autonomous subnetworks, or "highly overlapping", meaning that the OXCs are defined as being included in more than one subnetwork. Each subnetwork restoration controller (SRC) includes a network graph and is therefore responsible for providing restoration around faults recognized in its own subnetwork.

Abstract: A loader 10 includes a loader boom having opposite sides defined by arms to each of which is pivotally mounted a portion of a parking stand assembly including a support leg and a strut with the pivot axis for the leg being spaced between the implement at the end of the boom and the pivot axis for the strut. The support leg includes a pair of sides connected together by a web so as to be generally H-shaped in cross section over a major portion of its length. The web contains an opening through which the strut extends with the strut being in the channel defined below the support leg web and both the support leg and strut extending along the underside of the loader arm when the parking stand is in its stored position. The channel defined above the web receives the lower portion of the loader arm. A  releasable fastener couples the strut to the arm, the strut in turn holding the support leg in place. When the fastener is released, the strut and arm gravitate toward a park position which is effected when a receptacle adjacent the end of the strut comes into engagement with a cross pin mounted to the support leg at a location close to the opening. The strut carries a hook which faces the receptacle and functions to prevent the support leg from strut from becoming withdrawn from the opening in the support leg web and thus separating from the leg.

Title: Integrated semi-active seat suspension and seat lockup system
Inventor: VANDERMOLEN GARY L
IPC: B60N2/52
Filed: 1999-10-06
Granted: 2007-03-20
Abstract: The vehicle seat suspension system of the present invention utilizes an extensible linkage supporting a seat frame. Height adjustment of the seat frame on the extensible linkage is done through an adjustable air spring. Movement of the seat frame due to jostling of the vehicle is normally dampened using a variable damping rate, extensible shock absorber. The damping rate is essentially pushed in infinity, fully locking the shock absorber positionally in response to detection of an accident condition. In one embodiment of the invention, a bleed valve between the compression and rebound chambers of the shock absorber is closed to effect lock up. In an alternative embodiment, the electrorheological or magnetorheological working fluid of a shock absorber may be solidified to lock positionally the shock absorber.  Condition detection sensors include accelerometers and roll over detectors. To allow for the possible loss of vehicle power, the lock up signal is supplied by an independent power source.

Abstract: The process to measure the signal quality of a digital information transmission system using a scanning device with adjustable direct current threshold can determine a signal parameter for the signal quality (Q-factor), which can determine the bit-rate from an unknown input signal and with its help a clock signal can be generated to scan the input signal with the scanning device. The device includes a detection device as well as a clock generator, which is connected to the detection device and receives a pre-adjustment signal, and which synchronises with the input signal over a phase locked loop with the scanning device through phase comparison. Process and device allow the monitoring of systems in a shortest time and facilitate statements concerning the bit-rate of the respective line section as well as concerning the size of the Q-factor and all relating variables.

Abstract: The composition as described serves for in vivo cartilage repair. It basically consists of a naturally derived osteoinductive and/or chondroinductive mixture of factors (e.g., derived from bone) or of a synthetic mimic of such a mixture combined with a nanosphere delivery system. A  preferred mixture of factors is the combination of factors isolated from bone, known as BP and described by Poser and Benedict (WO 95/13767). The nanosphere delivery system consists of nanospheres defined as polymer particles of less than 1000 nm in diameter (whereby the majority of particles preferably ranges between 200-400 nm) in which nanospheres the combination of factors is encapsulated. The nanospheres are loaded with the mixture of factors in a weight ratio of 0.001 to 17 % (w/w), preferably of 1 to 4% (w/w) and have a release profile with an initial burst of 10 to 20 % of the total load over the first 24 hours and a long time release of at least 0.1 per day during at least seven following days. The nanospheres are composed of e.g.  ((D,L)-lactic acid/glycolic acid)-copolymer (PLGA). The loaded nanospheres are e.g.  made by phase inversion. The composition is advantageously utilized as a device comprising any biodegradable matrix in which the nanospheres loaded with the factor combination is contained.

Abstract: A system and method for processing call signaling to determine if a call is a ported call or a non-ported call. A signaling processor determines if a ported number parameter (PNP), such as a forward call indicator (FCI) bit M and/or a ported number generic address parameter (GAP), is present. If the PNP is not present and the signaling processor determines the dialed number is a member of a portable number plan area and central office code combinations (NPA-NXX), the signaling processor queries a ported number database (PNDB). The PNDB responds with the called number dialed digits if the call is not a ported call or a location routing number (LRN) if the call is a ported call. The signaling processor appends a 1 to the nature of address (NOA) subfield of the called party number (CdPN) field if the call is a ported call. The signaling processor then partitions the call signaling parameters between ported or non-ported routing table translations, depending on whether the NOA is appended or not, to determine call routing connections and new call signaling. The appended 1 of the appended NOA is removed prior to building an outgoing call signaling message.
