Title: Digital signal synchronization employing single elastic store
Inventor: KRAMER ERIK J
IPC: H04J3/00
Filed: 1991-02-12
Granted: 1995-02-21
Abstract: An incoming data signal including so-called gaps is synchronized to a new outgoing clock signal by employing a single elastic store and a smooth writeaddress. An elastic store write address is generated in response to an incoming clock signal and is inhibited from advancing during the gaps in the incoming data signal. A smooth clock signal is obtained by appropriately dividing the incoming clock signal by a value dependent on the duration of the gaps in a predetermined portion of the incoming data signal. The smooth clock signal is used to control a counter to generate a smooth write address. The smooth write address is supplied to a phasedetector. An adjusted read address is generated in response to the new outgoing clock signal and is supplied to the elastic store and to the phase detector. A counter used to generate the adjusted read address is inhibited from advancing during intervals in which gaps are to appear in the output data signal from the elastic store. A stuff decision is made at predetermined stuff decision points which are strategically placed relative to the positions of the gaps to be inserted in the outgoing data signal so that apparent jumps in a write-read separate signal generated by phase detector do not affect the stuff decision.

Title: Composite electric and optical cable manufacture
Inventor: HOGG CLIVE LAURENCE
IPC: H01B13/00

Granted: 1998-06-30
Abstract: In a simple and inexpensive method of manufacturing a composite electric and optical cable incorporating a flexible tube having a flexible optical waveguide loosely housed in the bore of the tube, the flexible electric cable, without a flexible optical guide loosely housed in the bore of the flexible tube, is wound around the hub of a cable drum in such a way that each end of the wound cable is exposed and accessible.  The flexible optical guide is then accommodated in the bore of the flexible tube of the wound cable by introducing a leading end of the optical guide into the end of the bore of the flexible tube at one exposed end of the wound cable and by propelling the optical guide along the bore of the wound cable by fluid drag of a gaseous medium which is passed through the bore in the desired direction of advance at such a pressure that the optical guide is carried along the bore until the optical guide is loosely housed in and throughout the length of the bore of the flexible tube of the wound cable.

Granted: 2000-10-31
Abstract: A thermal imager testing device (10) incorporates a pattern plate (32) with patterns (P0, P1, P2 and P3) cut through it. Patterns (P0 and P1) are of like spatial frequency, whereas patterns (P2 and P3) have respective relatively higher spatial frequencies. The patterns (P0 to P3) are like structured and like oriented, and they underlie blackbodies (34, 26, 28 and 30) respectively.  Temperature differentials between the blackbodies (34 and 26 to 30) are maintained at constant values by temperature control circuits. The temperature of blackbody (34) is adjustable. The pattern plate (32) and underlying blackbodies are viewed by a thermal imager under test. The temperature of the blackbody (34) is adjusted until pattern (PO) is just discernable as cold relative to the pattern plate (32). If the thermal imager performance is acceptable patterns (P1 to P3) are then just discernable as hot relative to the pattern plate (32).

Granted: 1997-01-07
Abstract: A mounting plate (20) is positioned between a manifold (18) and a pair of fluid pressure transmitters including a differen-tial pressure transmitter (22) and a gauge pressure transmitter (24). The fluid pressure from high and low pressure taps or lines (14, 16) placed on opposite sides of a flow restriction (12) of a main flow line (10) is measured and transmitted to a remote loca-tion by the transmitters (22, 24). The mounting plate (20) has low and high pressure ports (62, 64) for differential pressure trans-mitter (22) and a low pressure port (66) for a gauge pressure transmitter (24). A connecting fluid passage (68) connects the low pressure ports (62, 66) and a block valve (80) is movable between open and closed positions to permit or block fluid communica-tion between the ports (62, 66) and fluid communication between the transmitters (22, 24). One pair of ports (66, 76) are arranged in symmetrical relation to the other pair of ports (62, 64) to permit the mounting plate (2) to be utilized with the gauge pressure transmitter (24) for measurement of either a low pressure or a high pressure.

Abstract: An automatic swimming pool chlorinator having a submersible canister for receiving and containing chlorine tablets or sticks. The canister, at its upper end, is provided with a separable lid which includes: a principal water flow conduit through which pool water is recirculated by suction to the pool's water filter and heater system or returned to the pool via a water return line; a multiplicity of small ports for admitting relatively small quantities of pool water to the canister to dissolve the chlorine therein over a period of time; a chlorinated water flow channel leading from the canister to the principal water flow conduit and through which chlorinated pool water is aspirated from the canister, and is mixed with, the flow of recirculated pool water in the principal water flow conduit; and a water flaw controller located within the chlorinated water flow channel to control the amount of chlorinated water aspirated from the canister and through such channel by the pool water being recirculated through the principal water flow conduit to the pool's filter and heater system.      The chlorinator may be mounted between sections of the water suction hose line leading from a pool cleaner unit to a pool skimmer. Alternatively, the chlorinator may be mounted at one end of its principal water flow conduit directly to a water recirculation return line at the side of the pool.

Inventor: RUSSO RONALD D
IPC: A61M25/00
Filed: 1993-07-02
Granted: 1996-09-10
Abstract: A retention bolster for a percutaneous catheter is disclosed having a convexly curved exterior surface which contacts the epidermal surface of a patient.  The retention bolster slides over a catheter until contacting the skin of the patient at the catheter exit site.  When secured in place, the retention bolster rocks along contacting portions between its convexly curved surface and the epidermal surface of the patient in response to movement of the catheter about the exit site, thereby alleviating the added pressure that would otherwise be applied by this movement.  Upon the release of lateral pressure against the catheter device, the bolster returns to its original upright position.  In a second disclosed embodiment, a flange is provided which extends from the main body of the bolster which defines a bore that is also sized for slidably receiving and supporting the catheter, and which provides for angled attachment of the catheter relative to its exit site.

Title: Post answer telephone call redirection or rerouting
Inventor: BURD MARGARET ANN
IPC: H04M3/56
Filed: 1993-11-16
Granted: 1997-04-08
Abstract: Calls made to an 800 service subscriber are routed to the subscriber's primary location via a telephone network switch operating in conjunction with a specially configured adjunct processor.  The adjunct processor is arranged to monitor the call even after it is answered by an attendant or other subscriber personnel at the primary location.  If the call is to be redirected from the primary location to an alternate location, the adjunct is signaled, typically by a DTMF sequence.  The adjunct responds by putting the calling party on hold and by initiating a call to the alternate location on an outgoing trunk of the network switch, in such a way that it emulates or imitates both the routing (call treatment) and billing the characteristics of a call made from the original customer location.  Redirection can then be completed in one of three ways: blind transfer, consultation, or conference.  Billing for the call is arranged so that the subscriber of the 800 number originally dialed by the calling party at the customer location pays only for the portion of the call in which the primary location is active.  The subscriber providing the 800 number for the alternate location pays for the portion of the call in which the alternate location is involved, as though the call originated from the customer's location and proceeded directly to the alternate location, without having been rerouted at the network switch. Thus, the subscriber is not charged for any period of time which is not "used" by that subscriber.
