Abstract: Technologies and techniques for displaying information for an occupant of a motor vehicle. The display position of a head-up display is able to be varied flexibly depending on the context. To this end, both a displacement of the X and/or Y position and a color selection adapted to the background may be implemented and be performed automatically. Information from the steering angle, speed, map data and also head tracking by the interior camera may be combined to determine the X and/or Y position. In order to achieve optimum visibility for any load case, sensor fusion from the position data and an exterior camera may take place: Content or information (24) may thus be displayed depending on the current display position, so as to be more visible. If only some of the information is on a background, only some of the color may also change.

Abstract: The present invention describes the use of discrete states and signatures for classifying samples.

Abstract: The invention is an electromagnetic wave or “EM” coupler for successfully connecting EM waves between an EM generator output and a conductive pathway or “c-pathway” that is not normally considered as an EM transmission medium or line. The coupler includes a dual surface shell-like structure with an electrically conductive outer surface that is insulated from an electrically conductive inner surface that is attached at a specified location along a c-pathway. The forward end of the inside surface of the coupler is attached to the c-pathway while the outside surface of the forward end of the coupler is left unconnected and open. To provide a successful EM connection between the coupler and the c-pathway, the physical size of the coupler is configured as a physically shaped component with a relationship to the c-pathway itself rather than to the particular EM wave required to make such connectivity.

Abstract: A method and system for a secure telephone protocol are disclosed, which can be implemented using current Voice over IP (VoIP) protocols, Session Initiation Protocol (SIP, as specified in the Request for Comment (RFC) 3261 from the Internet Engineering Task Force (IETF)), Real Time Transport Protocol (RTP, as specified in RFC 3550), and Secure RTP (SRTP, as specified in RFC 3711). The secure telephone protocol can include a shared secret value that is cached and then re-used later to authenticate a long series of session keys to be used for numerous separate secure phone calls over a long period of time, thereby providing cryptographic key continuity without the need for voice authentication. In an embodiment, the secure telephone protocol can utilize the Diffie-Hellman key exchange during call setup, and AES for encrypting the voice stream.

Abstract: A cryptosystem is described which automatically provides an extra “message recovery” recipient(s) when an encrypted message is generated in the system. The system is typically configured such that the extra recipient or “message recovery agent” (MRA)—an entity which itself has a public key (i.e., a MRA public key)—is automatically added, under appropriate circumstances, as a valid recipient for an encrypted message created by a user. In a corporate setting, for example, the message recovery agent is the “corporate” message recovery agent designated for that company (firm, organization, or other group) and the user is an employee (or member) of that company (or group). In operation, the system embeds a pointer (or other reference mechanism) to the MRA public key into the public key of the user or employee, so that encrypted messages sent to the company's employees from outside users (e.g., those individuals who are not employees of the company) can nevertheless still be recovered by the company.

Abstract: A microphone holder for surveillance work and adapted to support a microphone in a concealed position when the holder is taped to the upper torso of a surveillance agent and to avoid clothing rustle and bulges resulting from the normal wear of the holder. The holder is of a flexible rubber material capable of moving with the wearer to permit comfortable use and avoid detection by persons under surveillance. The holder has an upper surface of a generally convex shape and a lower surface which is nearly flat but slightly concave. The upper surface is provided with a recess for the retention of a small microphone that can be un-encased and recessed below the upper surface to avoid clothing rustle. Microphone leads are kept below the upper surface in a groove to further avoid a detectable impression through the clothing of a wearer. Recording means which may include transmitting means is typically located elsewhere on the wearer.
