Abstract: In one embodiment, a touch sensor includes a substrate and a mesh of conductive material formed on the substrate and configured to extend across a display. The mesh of conductive material comprises first lines of conductive material that are substantially parallel to each other. The first lines are configured to extend across at least a portion of the display at a first angle relative to a first axis. The first lines are separated from each other along the first axis by a sequence of separation distances. Magnitudes of more than one of the separation distances are based on a phasor comprising at least one side band, wherein the at least one side band comprises at least one positive side band component and at least one negative side band component. The magnitudes comprise a pattern of translational shifts.

Abstract: A system for implementing a content protection protocol to encrypt data, including transmitters and receivers to which key selection vectors of a vector set have been distributed, wherein a subset of the key selection vectors in the vector set has not been distributed to any of the transmitters or any of the receivers, and a method for enabling transmitters and receivers to implement a content protection protocol including by distributing key selection vectors of a vector set, and private key sets, to the transmitters and receivers while reserving a subset of the key selection vectors of the vector set.

Abstract: A communication system including a transmitter, a receiver, a communication link (for example, a TMDS-like link), and preferably also an external agent with which the transmitter and receiver can communicate, in which video data (or other data) are encrypted, the encrypted data are transmitted from the transmitter to the receiver, and the transmitted data are decrypted in the receiver, a transmitter and a receiver for use in such a system, a cipher engine for use in such a transmitter or receiver, a method for operating such a transmitter or receiver to encrypt or decrypt data, and a method for distributing keys to the transmitter and receiver. The receiver can be a player coupled to a downstream receiver by a TMDS-like link, and configured to re-encrypt the decrypted data (for example, using an AES or HDCP protocol) and send re-encrypted data over the link to the receiver.

Abstract: In some embodiments, the invention is a personal digital network (“PDN”) including hardware (sometimes referred to as Ingress circuitry) configured to transcrypt encrypted content that enters the PDN. Typically, the transcryption (decryption followed by re-encryption) is performed in hardware within the Ingress circuitry and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the Ingress circuitry. Typically, transcrypted content that leaves the Ingress circuitry remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits or is otherwise easily accessible by software, until it is decrypted within hardware (sometimes referred to as Egress circuitry) for display or playback or output from the PDN.

Abstract: A method for adaptively filtering a control signal in a serial link includes monitoring for a blanking interval in a video stream having an associated clock signal and monitoring for an occurrence of a VSNYC signal once the blanking interval has started. A control signal is initially detected wherein the control signal occurs subsequent to the occurrence of the VSNYC signal. A set of properties of the control signal are recorded and a set of filter parameters are adjusted for detecting the control signal in a next blanking period based on the set of properties of the control signal.

Abstract: A communication system including a transmitter, a receiver, and a serial link (for example, a TMDS-like link) in which video data (or other data) are encrypted, the encrypted data are transmitted from the transmitter to the receiver, and the transmitted data are decrypted in the receiver, a transmitter and a receiver for use in such systems, a cipher engine for use in such a transmitter or receiver, a method for operating such a transmitter or receiver to encrypt or decrypt data, and a method for authenticating a receiver prior to transmission of encrypted data to the receiver over a serial link. Each transmitter, receiver, and cipher engine is configured to implement a content protection protocol in a manner that implements at least one and preferably more than one of a class of attack prevention features disclosed herein.

Abstract: A system including at least one transmitter, at least one repeater (including a router) and optionally at least one receiver, and typically having a tree structure. Commands (each accompanied by an address) and data can be transmitted downstream from each transmitter to each repeater coupled thereto and from each repeater to each device coupled thereto. Preferably, each router is assigned a router access address (that is shared with other routers) and a unique router address. In response to the router access address and a management command, the router performs a management function. Preferably, each repeater has at least one other common address (e.g.
