Abstract: A method for disabling a process in a computer, particularly including processes such as viruses, spyware, adware, and malware generally. A file object (file or folder) is identified in the computer that is required by the process. An access control entry (ACE) is then stored in an access control list (ACL) for the file object. The ACE specifies an entity (user or group) and a permission needed by that entity to access or execute the file object. The ACE further specifies that the entity is denied the permission it needs. This disables the process by denying the entity the future ability to access or execute the file object.

Abstract: An invention is provided for monitoring an item, such as a container. The invention includes a computer in communication with a receiver that receives signals from a remote source. A transmitter in communication with the computer receives values from the computer based on the signals received from the remote source. These values are then transmitted to a security device associated with the item, which includes an authentication table comprising a plurality of initial values. The security device then records values transmitted from the transmitter. The values can be jitter values, with each jitter value being a difference in arrival times of at least two timing signals from the same remote source.

Abstract: A system (50, 150) for assisting a user (14) to determine whether a hyperlink (152) to a target uniform resource locator (URL) is spoofed. A computerized system having a display unit is provided and logic (158) therein listens for activation of the hyperlink (152) in a message (154).

To enhance accuracy, a plurality of battery response voltage curves can be calculated, each based on voltage differences between battery response voltage readings taken along the waveform. The battery polarization point can then be identified when the slopes of all the battery response voltage curves stop increasing at an increasing rate.

Abstract: A mode transducer for converting an electromagnetic wave between TE1,0 and TM0,1 modes. A rectangular waveguide guides the wave while in TE1,0 mode and a circular waveguide guides the wave while in TM0,1 mode. The rectangular waveguide and the circular waveguide are joined by a chamber to form a right angle structure. The chamber particularly includes offset walls distended away from proximal portions of the rectangular waveguide to convert the electromagnetic wave between modes. Two of the mode transducers rotatably coupled with a suitable rotation mechanism may be used as a rotary waveguide joint.

Abstract: A waveguide orthomode transducer. In a first layer a turnstile junction having a main waveguide and four waveguide ports, and four hybrid tees each have an e-port, two opposed side-ports, and an h-port. The hybrid tees are ring-arranged around the turnstile junction so the waveguide ports each communicate with one h-port, so adjacent hybrid tees inter communicate with their respective side-ports, and so the e-ports form two sets of opposed e-ports. In a second layer two h-plane power dividers/combiners each have an axial-port and two opposed side-ports. The h-plane power dividers/combiners are arranged so their respective side-ports communicate with different ones of the two sets of opposed e-ports and so their axial-ports are polarization ports. This permits a single signal with two fundamental orthogonally polarized modes to enter the main waveguide and exit separated at the polarization ports vice versa.

Abstract: A communication system (410) wherewith sources (414) and targets (416) employ a key server (420) to exchange transactions (424). A first request to the key server includes a source assertion (422) from an authentication authority (418), and optionally a key (430). The key server provides a transaction ID (428), and the key if not already provided, in reply to this request. The key server stores the transaction ID and source assertion. The source encrypts the transaction and sends it with the transaction ID to the targets. A second request to the key server includes a target assertion and the transaction ID. The key server provides the key in reply to this request. The key server also stores the target assertion in association with the transaction ID. The respective assertions then establish the source and targets of the transaction in a manner that cannot plausibly be repudiated.

Abstract: An invention for digital authentication is provided. A first timing signal is received from a remote source using a receiver. Next, a delay number is stored. The delay number is based on a first delay time period between when the first timing signal was transmitted and when the first timing signal was received. A digital transaction is then authenticated using the delay number. In one aspect, a digital certificate is created using the delay number. The remote source can be any source capable of generating timing signals, such as a global positioning satellite (GPS) system or a cell tower system. The delay in the timing signal can be caused by free electrons in a line of sight between the remote source and the receiver, such as by variations in atmospheric conditions or by an object within the line of sight such as bird or tree branch. Optionally, the delay number can be stored on a User Card and a System Card.

Abstract: Disclosed in the field of the four-cycle reciprocating piston internal combustion engine is an invention for a rotary ported intake and exhaust system and super-atmospherically charged on demand engine. This invention replaces the inefficient reciprocating valve system with a friction free rotating shaft with ports and passageways to produce the four cycles of the engine. It also replaces the accessory externally mounted compressors now used to super charge the engine by the use of two cylinders sharing the same minimum volume totally closed crankcase. As both pistons travel upward, they draw in air or air/fuel or that amount desired through a throttle body into the crankcase. As they travel downward, that cylinder on its intake cycle draws in air/fuel while the volume in the crankcase is compressed. Prior to the completion of the intake cycle, the crankcase pressure is released into that cylinder on its intake cycle super-atmospherically charging it. These cycles are then repeated for the other cylinder.
