Abstract: A shelf management device including a guide member having a front end and a rear end, and a pusher device guided for movement by the guide member. Wherein the pusher device includes a rotatable spool upon which is wound a flexible drive member, an end part of the drive member being secured to the guide member at or adjacent the front end thereof. A spring is provided to urge the spool for rotation to take up the drive member and thereby apply a load to the pusher device urging the pusher device towards the front end of the guide member.

Abstract: Systems and techniques can include one or more computer-implemented methods that include: digitally signing Universal Resource Locator (URLs), which have been isolated from a source playlist document, to generate digitally signed URLs; generating a protected playlist document from the digitally signed URLs; and providing the protected playlist document for use in a video on demand system. The digitally signed URLs can be in a protected master playlist document and can point to two or more sub-playlist documents, which can themselves be protected. The digitally signed URLs can be in a protected sub-playlist document and can point to encrypted video fragments. In addition, a URL of the protected master playlist document can itself be digitally signed, and the digitally signed master playlist URL can be sent to a mobile device in response to a request for video from the mobile device.

Abstract: An aspect of the subject matter described in this specification can be embodied in one or more computer-implemented methods that include obtaining a master playlist document including references to sub-playlist documents that reference video documents of different video quality for use in a video streaming on demand system, parsing the master playlist document to extract the references, digitally signing the references, generating a protected master playlist document from the digitally signed references, and providing the protected master playlist document for use in the video streaming on demand system.

Abstract: A system and method for providing secure access to a computer system. An access device divides the password into multiple segments and places them in data packets. In one embodiment, an authentication server has multiple addresses, and each packet is sent to a different address. The server then reassembles the password. In another embodiment, when the server receives a password, the server sends an index value back to the access device, which then accesses the server on another address indicated by the index value. Alternatively, the password is sent to multiple addresses for the server, and the server determines whether any of the received packets have been altered. The multiple password packets may be forced to follow different paths to the server, thereby denying hackers the ability to intercept all of the password characters or determine the inter-packet timing factor. The system is effective against passive and active hackers, Trojans, and phishing techniques.

Abstract: An apparatus, system, and method for constructing, transmitting, and authenticating a password utilized by an authentication device to authenticate an access device. The authentication device receives the password from the access device, authenticates the access device if the password matches stored information, and returns an acknowledgment message that includes an index value associated with a stored character set. The access device constructs and transmits the password. The access device receives from a user, a plurality of predefined characters forming a User ID. The access device also receives the acknowledgment message and index value from the authentication device. The index value is used to identify a character set from a plurality of character sets stored in a lookup table. The access device integrates the User ID and the identified character set to generate a password, and transmits the password to the authentication device.

Abstract: A client device, system, and method for constructing a two-factor password utilized by an authentication device to authenticate an accessing computer. The client device connects to the accessing computer through an input/output (I/O) port such as a USB connection. When a user desires to access a network, he enters a user ID, which is sent from the accessing computer to the client device. The client device includes a client application, which retrieves a second factor from an internal database, and combines the user ID and the retrieved second factor to form the two-factor password. The two-factor password is sent to the accessing computer, which transmits it to the authentication device. The accessing computer is authenticated only if both the user ID and the second factor match a user ID and second factor stored in the authentication device.

Abstract: A system and method for generating and authenticating a password to protect a computer system from unauthorized access. The characters of the password are placed in data packets by an access device. Prior to sending the packets, the device inserts predefined time intervals between each of the data packets. The value of the time intervals is retrieved from a sequence of time intervals that is shared between the access device and an authentication device. The authentication device determines whether the received set of password characters matches a stored set of password characters, measures the time intervals between the packets, and determines whether the measured time intervals match the predefined time intervals. The authentication device positively authenticates the access device only if both the characters and the time intervals match. Periodically, different time intervals from the sequence are inserted to change the password.

Abstract: Described is an interior trim panel (20) and method of manufacturing same comprising the steps of: providing a foam trim panel (22), treating the foam panel with a coating composition containing a polymerizable polymer, and an organofunctional silaceous material; and shaping and curing the treated panel to a desired configuration so that the organofunctional silaceous material reacts and cures to assist in the foam panel retaining its desired configuration.

Abstract: A nozzle assembly (16), for spraying a liquid such as a urethane prepolymer on a substrate, has a liquid spray nozzle (28) with a center line (56). Air nozzles (30), with center lines (62) that are substantially parallel to the center line (56) of the liquid spray nozzle (28), are provided in the nozzle assembly (16) around the liquid spray nozzle. Air passing from the air nozzles (30) surrounds and encloses the liquid spray and decreases the size of the liquid spray fan pattern (58 or 70). The air spray nozzles (30) can be positioned in the nozzle assembly (16) to change the shape of the liquid spray fan pattern (58 or 70) as well as the size. Mixing of air and liquid is minimized by spraying air and liquid in parallel paths.

Abstract: A system for constraining a moving device to parallel plane translational movement, the system including a base; a frame fixed to the base and including frame portions disposed at the periphery of a region; a movable device disposed in the region; and a plurality of coupling elements connected between the frame portions and the movable device so as to provide support thereof, each of the coupling elements being capable of bending motion and incapable of twisting motion so as to guide movement of the movable device along a path including a series of planes all oriented substantially parallel to each other. The coupling elements restrict movement of the device to a desired sequential parallel plane path.

Abstract: A pivoting, compensating parallelogram linkage system converts rotary motion into axial linear motion of a portion thereof suited for critical uses such as carriage of a moving mirror in a Michelson interferometer. The compensating includes a coupling provision that in response to angle change in one part of the linkage imposes an equal but opposite angle change in another part of the linkage. The coupling may include a motor to reciprocate the portion usable as a carriage.

Abstract: A system for reducing wavelength error caused by angular motion of the moving mirror of an interferometer, such as a Michelson interferometer having fore-optics introducing a beam of radiant energy for impingement on the moving mirror, teaches reducing, without necessary loss of energy, the width of the beam before impingement on the moving mirror; other advantages also accrue to use of the reduced width beam, such as facility in use of absorption cells and multiplying clear path length, when desired.
