Publication number: 20120102575Abstract: A method and system for securing digital content for transmission to an end user device. In a preferred embodiment, the invention provides for: a control center for controlling access to the digital content by the end user device; transmitting scrambled digital content to the end user device, such that the end user device cannot play back the said scrambled digital content; contacting the control center to request a PECM (personal ECM), the PECM being specific to the end user device; transmitting the PECM to the end user device by the control center; and unscrambling the scrambled digital content by the end user device according to the PECM.Type: ApplicationFiled: November 30, 2011Publication date: April 26, 2012Inventors: CHAIM D.

Publication number: 20080205640Abstract: A system and a method for flexible, yet secure distribution of digital content items, optionally with an automatic payment mechanism for purchasing such content. The present invention supports the distribution of content to end user devices from a central distribution point, as in client-server models and variations thereof, and/or peer-to-peer distribution, for example between end user devices. In addition, the present invention also supports distribution models within either of these mechanisms for unitary distribution, to a specified end user device, or broadcast/multicast distribution, to a plurality of end user devices. In any case, in order for the distributed content to be operative, for example to be “played back” or otherwise displayed, the recipient end user device must be in communication with a network control center.Type: ApplicationFiled: April 30, 2008Publication date: August 28, 2008Inventors: Chaim D.

Patent number: 4638250Abstract: A position sensor device is provided which inductively measures the change in position of a shorted conductive loop coil that is oriented to move in conjunction with the machine part to be measured relative to a stationary assembly. The stationary assembly is made up of a magnetic field generator and a sensor, which are oriented to respectively create and receive the magnetic field which is coupled to the loop. As a result, displacement of the coupling coil varies the degree of coupling between the generator and sensor such that the magnitude of the induced electrical current is representative of the location of the loop relative to the stationary assembly. The device can be used for measuring angular rotation, linear position and the angle of rotation, and linear movement with respect to displacement from a predetermined null position.Type: GrantFiled: January 30, 1984Date of Patent: January 20, 1987Assignee: Fiscint, Inc.Inventors: Chaim D.
