Abstract: An electrical control wiring system in which mains voltage (115 volts to 600 volts) power loads in a home or in a commercial building are controlled by use of extra low voltage devices such as switches, variable resistances and microcontrollers.  Wires are routed from an electrical panel and looped between special electrical device enclosures that in some respects resemble conventional electrical outlet boxes. The special electrical device enclosures are located in walls so that the front edges appear flush with the finished wall as would be the case with a conventional electrical outlet box in a finished room. The mains voltage wiring is done in the manner normally used in mains voltage wiring. Multi-conductor extra-low voltage cable such as Category 5 cable is routed from a control location and looped to the same special electrical device enclosure locations. The special electrical device enclosure has a plate, which is removable from within the special electrical device enclosure and once this plate is removed, a large opening is present in one wall of the special electrical device enclosure. The extra-low voltage wiring is accessible through the large opening in one wall of the special electrical device enclosure. The extra-low voltage cables may be pulled out through the open front of the special electrical device enclosure and connected to the controlling connections of a controlling device. The controlling device contains components that provide control of the load and a means of electrically separating the mains voltage system from the extra-low voltage system. The controlling device has a plate of size and shape similar to the plate removed from the special electrical device enclosure. An orifice is present in the plate that is part of the controlling device and controlled connections pass through this orifice to connect to components such as a power relay or a triac. When the controlling device is inserted in to the special electrical device enclosure through the front opening of the special electrical device enclosure, physical separation of the mains voltage wire and the extra-low voltage wires is achieved. The controlled connections are present in the special electrical device enclosure for connection to the mains voltage wires and to the mains voltage load. The extra-low voltage cables are accessible by removal of the controlling device or by removal of the plate.

Abstract: A novel lymphocyte receptor protein, its DNA sequence, and its role in the calcium activation pathway is described. The protein, or genetically engineered constructs encoding it, are shown to increase lymphocyte response, and to identify ligands of the protein receptor. Antibodies to the proteins of the invention are generated for diagnositc therapeutics. The protein and DNA can also be used for diagnostic purposes and for identifying agents for modulating the calcium induced activation pathway. A particular advantage of the present invention is that it provides lymphocyte activation of receptor found on all B cells, but only on a subset of T cells. The receptor can thus be targeted to specifically regulate B cell responses without affecting mature T cell activity. Such targeting specificity is always advantageous, particularly where an increase or decrease of antibody production is desired, e.g., during an infection (increase) or to avoid immune complex deposition complications (reheumatoid arthritis, glomerulonephritis, and other autoimmune conditions).

Title: Automatic firearm user identification and safety module
Inventor: AZELMAD ABDELLAH
IPC: F41A17/06
Filed: 1999-11-24
Abstract: An automatic firearm safety system where power consumption is reduced and safety is increased is disclosed. The system includes a movement detector operatively associated with a trigger of a firearm for detecting movement of the trigger. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when movement of the trigger has been detected. The coded signal is received by at least one remote token which receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A solenoid is also provided for locking and unlocking the trigger, operatively associated with the transceiver for allowing operation of the trigger and thereby the firing of the firearm when the coded acknowledgement signal has been received by the transceiver. The system may include two tokens, both of which are worn by the authorized user. In this case, the transceiver further includes an anti-collision module to discriminate between the different tokens and select which one will be permitted to issue the coded acknowledgement signal. Also preferably, the transceiver includes an anti jamming module. Since verification of the token is done every time the trigger is depressed, safety is increased.  Furthermore, since bi-directional RF communication is effected only when the trigger is depressed, power consumption is reduced.

Title: Intravaginal catamenial device for blood leakage prevention
Inventor: ZADINI GIORGIO C
IPC: A61F13/20
Filed: 1998-08-07
Abstract: An intravaginal catamenial device (1) for prevention of leaking of menstrual blood composed of an absorbent member (3) and of an inflatable menstrual cup (2). The tampon absorbs menstrual blood while the inflatable menstrual cup (2) has the dual function, once inflated, of collecting menstrual blood within its cavity or reservoir (14) and of providing sealable closure of the vaginal canal for the prevention of exit through the vaginal orifice of menstrual blood escaped to the absorption of the tampon. By being inflatable, menstrual cup (2) allows an easy insertion and an easy removal of the device when deflated and it is also capable, upon extraction and disposal, of sealing off the blood collected, closing its opening (16) around tampon (3). The inflation of the menstrual cup (2) can be conveniently initiated during or just prior to insertion into the vagina by the user due to activation of a simple and safe chemical reaction which generates a gas such as CO2. The apparatus of inflation (10) is conveniently housed within inflatable menstrual cup (2). No external pneumatic sources are needed. Completion of inflation of the menstrual cup (2) occurs without operator intervention with the device already inserted into the vagina. Deflation of the menstrual cup (2) and extraction of the device from the vagina is carried out by the operator by pulling on a string (70) connected to the device. Pulling on the string (70), deflates the menstrual cup (2) and allows easy removal of the device. The device is user friendly, easy to insert and remove and comfortable to wear.

Title: Mortise latch and exit device with concealed vertical rods
Inventor: PICARD DANIEL
IPC: E05B63/08
Filed: 2000-02-25
Abstract: A mortise latch and exit device includes active and passive mortise latch mechanisms with corresponding concealed vertical rods operated by links mounted within the mortise latch mechanisms. The mortise latch mechanisms latch double doors at a center point between the doors and at top points between each door and the door frame. Lower vertical rods may also be used to latch at bottom points between the doors and the floor. The active and passive mortise latch mechanisms are operated by corresponding push handle mechanisms and rotary handles. The mortise latch mechanisms cooperatively interact so that either door may be opened first, and either door may be closed first, without regard to the position of the other door. The active mortise latch mechanism includes a latch bolt and an activation bolt arranged so that one bolt is retracted when the other is extended, except when the doors are being opened or closed, when both bolts are retracted. The active mortise latch mechanism automatically retracts the latch bolt when the doors are not aligned and automatically extends the latch bolt when the doors are aligned.   The passive mortise latch mechanism ejects the latch bolt as needed to allow the passive door to be opened first.
