An error condition, fault, defect, obstruction, or defective arrangement of viewing angle is determined in a target security device, such as a motion sensor. A plurality of times a fault is detected in a first security device arranged to sense activity in a first zone, the target security device being arranged to sense activity in a second zone overlapping with the first zone; and the error condition may be determined in the target security device when fault in the target security device is not detected for the plurality of times. The second zone may overlap substantially all of the first zone. The first security device may be a door security sensor, a gate security sensor, a keypad or a motion detector. When the first security device is a keypad or user interface, the fault may be an arm or disarm command or an arm/disarm command cycle.

A virtual receiver having multiple communication ports for connecting a link to a plurality of local security systems. The virtual receiver is programmed with a virtual receiver number and a virtual line number for each physical communication port on the receiver. The virtual receiver has a master/slave operational mode such that the data received from the plurality of local security systems by each receiver is transmitted from at least one selected slave receiver to a selected master receiver. The virtual receiver number and virtual line number is used to create a part of a subscriber number. In master/slave operation mode, M number of receivers are linked together and the possible number of virtual receiver lines in a virtual receiver is M times the number in a normal mode of operation.

A system diagnostic mode is provided for a security central station receiver that monitors the operations of a large number of individual security systems over a large number of telephone lines. The system diagnostic mode provides the receiver with the capability to test itself for proper operation after it has been initially installed, or on a repeated basis thereafter, to ensure that the receiver at the security central station is fully operational. A plurality of line cards are designed to serve and interface with the large number of telephone lines. The auto test diagnostic mode tests the operation of the central station receiver, and is programmed to automatically dial into each of the plurality of line cards and to send to each line card a number of preformatted test signals using standard reporting formats that are generated by the auto test diagnostic mode. The auto test diagnostic mode is preferably provided on a test line card that generates the preformatted test signals. After the test is completed, the auto test diagnostic mode routes a report on the results of the preformatted tests to an output of the security central station receiver such as an automation system.
摘要:
A sequential storage device and method for storing boot image data and for booting. Data, such as a tag or flag, indicative of boot image data is stored in non-volatile memory associated with the sequential storage medium. When the sequential storage medium is loaded the presence of the data is checked in order to determine whether boot image data is stored on the sequential storage medium or not. If boot image data is present, the sequential storage device starts emulation of an initial program load device.

RSVP host proxy services for extending RSVP-signaled QoS provisioning to flows involving one or more RSVP-unaware hosts. In an RSVP sender host proxy service, a switch through which an RSVP-unaware source host accesses a network acts as an RSVP sender host proxy for the source host. In an RSVP receiver host proxy service, a switch through which an RSVP-unaware destination host accesses a network acts as an RSVP receiver host proxy for the destination host.

1, 2-dioxetane compounds bearing a proteolytic enzyme specific amino acid or peptide are provided, which amino acid or peptide can be removed by action of the corresponding protease. When the amino acid or peptide is removed, the 1,2-dioxetane decomposes with chemiluminescence, the generation of light providing a rapid, ultra-sensitive and convenient means for detecting the presence of the protease in the sample being inspected. The amount of light generated, or degree of chemiluminescence, can be correlated with the amount of protease present. Immunoassays, as well as DNA hybridization and DNA probe assays are provided.
摘要:
Probes labeled with 1,2-dioxetane precursors can be employed in a variety of assays. The probes may be nucleic acid, peptide nucleic acid, proteins including enzyme, antibody or antigen, steroid, carbohydrate, drug or non-drug hapten. The probe is provided with a 1,2-dioxetane precursor bound thereto, generally either covalently, or a strong ligand bond. The dioxetane precursor moiety is converted to a bound 1,2-dioxetane by exposure to singlet oxygen. These dioxetane (labels) either spontaneously decompose, or are induced to decompose by an appropriate trigger to release light. The trigger may be a change in pH temperature, or an agent which removes a protective group. Assay formats in which these 1,2-dioxetane labeled probes and referents may be used to include hybridization assays, immuno assays, gel-based assays and Capillary Zone Electrophoresis.
