A DVR, server, or other agent correlates media metadata from diverse sources, like an EPG data provider and multiple video-on-demand (VOD) service providers. Metadata sets from different sources are compared in order to attempt to identify identical programs to which the metadata sets pertain. From at least one metadata set, information about the program that the other metadata set lacks is selected. A “canonical” data structure instance for the program is created. The information that is lacking from at least one of the metadata sources is inserted into that instance. For each source from which a program is available, the DVR stores the identity of that source on the DVR's persistent storage device in association with the canonical data structure instance for that program. The DVR receives search criteria from a user and then searches the stored canonical data structure instance for programs that satisfy the criteria.

Computer readable media and methods are provided for initiating a failover state in a network element. A failover is when the element's traffic is routed to a redundant element which takes over the functions of the element, and any session state information stored in the element is also transferred to the redundant element.

The present invention is to provide an engaging structure applicable to a display device and including a housing and an inflatable element, wherein the housing serves as a protective case of the display device and is formed with at least one assembly hole, and the inflatable element is formed with at least one connecting portion, such that, when the housing is assembled into an accommodating space of the inflatable element and the inflatable element is fully inflated, the connecting portion is engaged in the corresponding assembly hole. Thus, the portions of the inflatable element that correspond in position to the accommodating space are tightly pressed against the sides of the housing other than the side where a screen is installed at the display device. Since the inflatable element is lightweight and occupies a tiny space while in a deflated state, it will effectively reduce storage space and transportation costs.

A computer system includes a rack-mountable server unit with a closed server housing. The server housing has a channel with a recessed channel wall in conductive thermal communication with a processor or other heat-generating component. An elongate conduit is received into the channel of the server housing in conductive thermal communication with an external surface of the server housing. The server is cooled by conductive fluid flow through the conduit, with no appreciable airflow through the server housing. The system may be operated in an optional burst cooling mode, wherein a volume of cooling fluid is trapped in the conduit for a period of time before being quickly released.

Electronic devices may have openings that serve as potential pathways for moisture intrusion into interior portions of the devices. An electronic device may be provided with moisture repelling coatings in the vicinity of these openings to help prevent moisture from reaching the interior of the device. The openings may be associated with gaps between adjacent housing structures, openings for buttons, openings for audio and connector ports or other openings in device structures. The moisture repelling coatings may be applied to housing surfaces, button members, structures associated with audio and connector ports, and other device structures.

A switching apparatus allows coupled coils to be dynamically switched in or out of a circuit using small control currents. The apparatus includes at least one latching circuit, one or more control circuits and diodes. The latching circuit may have two bipolar transistors connected in a transistor latch configuration with at least two diodes, such that at least one diode may be connected in series with a base of the each bipolar transistor. The control circuits may be connected to the latch circuit for operating the bipolar transistors. The diodes may be connected in the circuit for protecting the latching and control circuits from being exposed to high voltages and currents during the turn-off or turn-on of the inductor coils. This allows overall efficiency levels to be maintained while changing the inductance of the circuit as per requirements. The circuits may be used in switch mode power supplies (SMPS).

A disk drive is disclosed comprising a disk comprising tracks defined by servo sectors, a head, and control circuitry comprising a servo control system operable to actuate the head over the disk based on the servo sectors. An estimated acceleration EstAccel of the head over the disk is generated based on at least one of the servo sectors. When the EstAccel is determined to be reliable, an estimated velocity EstVel of the head over the disk is generated based on the EstAccel. When the EstAccel is determined to be unreliable, the EstAccel is adjusted to generate an adjusted acceleration AdjAccel and the EstVel of the head over the disk is generated based on the AdjAccel.

Described embodiments provide a method of cancelling inter-track interference (ITI) from one or more sectors read from a desired track of a storage medium. A read channel reads sectors in a desired track of the storage medium. An iterative decoder of the read channel decodes the read sectors, and if the read sectors are incorrectly recovered from the storage medium, selected sectors of a first adjacent track are read. An ITI canceller of the read channel estimates ITI in the read sectors of the desired track corresponding to the selected sectors of the adjacent track and subtracts the estimated ITI of the adjacent track from the data for the sectors of the desired track, providing updated sector data. The ITI cancelled data is replayed to the iterative decoder, which decodes the ITI cancelled data and provides the decoded ITI cancelled data as output data of the read channel.

An apparatus for indicating working states of hard disks includes a south bridge chip, a CPLD controller chip, a BMC chip, and indicating lights. The south bridge chip stores hard disk information of the hard disks. The CPLD controller chip reads position signals and data signals from the hard disk information and converts the position signals and the data signals into working states signals of the hard disks. The BMC chip receives the working states signals. If working states of the hard disks changes, the BMC chip converts the working states signals into changed position signals and changed data signals. The corresponding indicating lights receive the changed position signals and the changed data signals and indicates the changed working states of the hard disks according to the changed position signals and the changed data signals.
