摘要:
A remote telemetry system utilizing dual communication pathways comprising low-cost remote communications devices operating on existing wire-based communications systems, wireless communications systems, and/or a combination thereof, to provide real-time reading and control of the remote telemetry units. A central controller directs the operation of the remote telemetry units and receives data from the remote telemetry units. The central controller is configured to utilize a conventional broadcast communications channel to transmit commands to individual remote telemetry units, each of which is assigned a unique identification code. Signals broadcast from the central controller are received at receivers associated with each remote telemetry unit, which performs a directed operation if a unique identification code included in the broadcast signal matches the identification code assigned to the remote telemetry unit. Each remote telemetry unit is provided with access to a conventional shared two-way communication pathway for return communication to the central controller. The shared two-way communication pathway is inactive unless specifically activated by a remote telemetry unit upon receipt of a signal from the central controller. In this manner, a large number of remote telemetry units may be provided with regulated access to a single shared two-way communications channel.
摘要:
The present invention is directed to a method of reducing the viability of a tumor cell involving administering a virus that is not a common human pathogen to the tumor cell. Preferably, the virus exhibits differential susceptibility, in that normal cells are not affected by the virus. This differential susceptibility is more pronounced in the presence of interferon. The tumor cell is characterized by having low levels, or no, PKR activity, or as being PKR−/−, STAT1−/− or both PKR−/− and STAT1−/−. The virus is selected from the group consisting of Rhabdovirus and picornavirus, and preferably is vesicular stomatitis virus (VSV) or a derivative thereof.

The present invention provides mutant viruses with a decreased ability to block nuclear transport of mRNA or protein in an infected cell which are attenuated in vivo. The mutant viruses of the present invention may also be capable of triggering the anti-viral systems of normal host cells while remaining sensitive to the effects of these systems. The present invention further provides for the use of the mutant viruses in a range of applications including, but not limited to, as therapeutics for the treatment of cancer and infections, as vaccines and adjuvants, as viral vectors, and as oncolytic and cytolytic agents for the selective lysis of malignant or infected cells.

A meter disconnect adaptor for assembly into a residential electric meter socket. The adaptor has a base with a peripheral configuration which allows it to be used with either a ringless type of meter box, or in a ring type of mounting, and has blade simulating members extending from one side of the base and resilient fingers extending from the other side of the base for receiving contact blades of the electric meter. In one embodiment of the invention the adaptor has a group of resilient fingers arranged to allow assembly of the meter therein in any one of a number of orientations.

摘要:
In one aspect, the invention provides methods for preferentially killing target proliferating cells in a host, such as cancer cells, by infecting host tissues with two or more strains of virus. The strains of virus may be selected to provide a synergistic and symbiotic effect, involving a contemporaneous lytic infection in the target proliferating cells. In selected embodiments, the viruses are selected so that expression of a first virulence factor in proliferating cells infected with the first virus increases the lytic effect of the second virus; and, expression of the second virulence factor in proliferating cells infected with the second virus increases the lytic effect of the first virus. The genomes of the first and second viruses may be selected so that they are incompatible for recombination between the viral genomes in cells of the host.

The present invention relates to therapeutic use of Myxoma virus. Myxomas virus can selectively infect cells that have a deficient innate anti-viral response, including cells that are not responsive to interferon and can be used to treat diseases characterized by the presence of such cells, including cancer.

The invention provides compositions and methods for treating neoplastic disease, such as cancer, with an oncolytic virus, such as VSV. A carrier cell is used to target a diseased tissue, and to cloak the oncolytic virus from surveillance by the subject's immune system during a targeting interval. Following delivery of the virus to the target tissue, the lysis of the carrier cell, and of the target cell, by the oncolytic virus, promotes an adaptive tumouricidal immune response. A wide variety of disparate carrier cells may be used, in conjunction with a promiscuous oncolytic virus having broad tropism, in an approach which facilitates successive treatments in which a new carrier will not be susceptible to an adaptive immune response mounted against previously used carriers. The promiscuity of the virus also facilitates lysis of carrier cells and target cells that are allogenic or xenogenic. The lytic phase of the carrier cell infection is staged so that the carrier is administered in an eclipse phase, and lysis follows the conclusion of the therapeutic targeting interval.
摘要:
A user input device is disclosed adapting the electronic components of a time-domain reflectometry material level sensor to replace traditional user input devices such as push-buttons, control knobs, and variable sliders. An electrical conductor is arrayed beneath an input panel, such that when a high permittivity or high conductivity material is placed in proximity to the conductor, the characteristic impedance of the conductor is altered at that point, reflecting electronic pulses transmitted through the conductor. The reflected electronic pulse is received by the associated electronics, and the position of the material along the conductor subsequently determined. By segmenting the conductor into virtual regions, each corresponding to an individual "button", discrete input may be received by the device based upon the placement of the material within specific virtual regions. Alternatively, the conductor may function as an infinitely variable "slider" control, with movement of the material along the conductor producing a proportionally varying output signal.
