An apparatus for supporting a tablet includes a case for receiving the tablet. A swivel includes a socket and a ball disposed and retained therein. The ball is selectively rotatable relative to the socket. The ball is coupled to the case and the socket is coupled to a mounting post. The mounting post is releasably fixed to a mounting bar. The mounting bar defines a mounting slot configured to fix the apparatus relative to a structure, such as a microphone stand or the like. The apparatus includes clamping mechanisms to enable a user to selectively fix and release the components of the apparatus such that a user can configure and fix the apparatus to a desired position for interfacing with the tablet, and then lock the apparatus in that desired position.

An engine compartment of an automotive vehicle is provided. The compartment comprises an internal combustion engine including an air intake manifold and an electrical storage battery. The battery is housed in a storage box and an air intake system supplies air to the air intake manifold and the battery storage box. The air intake system has an inlet supplying air to a flow diverter. The flow diverter has a main channel including a bend dividing the main channel into a first passage and a second passage tangential to the first passage. The second passage is in fluid communication with the air intake manifold. The flow diverter includes an outlet facing the first passage which is in fluid communication with the battery storage box.

The disclosure provides a system and method for adjusting a backlight level for an image being displayed on an electronic device. The system comprises: a display for displaying an image to be backlit; memory storing a numeric representation of the image on a pixel-by-pixel basis; and a backlight adjustment module to calculate a pixel-by-pixel, running average of an intensity of the image using the numeric representation and to determine a backlight level for the image using the running average, the running average being calculated according to an equation that calculates a new average using a previous average and a current pixel intensity value to avoid an overflow condition when calculating the running average.

The present invention is directed to certain hydroxamate derivatives that are useful in the treatment of hepatitis C. These compounds are also inhibitors of histone deacetylase and are therefore useful in the treatment of diseases associated with histone deacetylase activity. Pharmaceutical compositions and processes for preparing these compounds are also disclosed.
摘要:
A polymer and coating composition containing the polymer are provided that are useful in coating applications such as, for example, food or beverage packaging containers. The polymer preferably includes a backbone having one or more polycyclic groups. In one embodiment, the polymer is a polyester and, more preferably, a polyester-urethane polymer. In one embodiment, the one or more polycyclic groups is a tricyclic or higher group.

A light emitter/sensor includes a lamp, a light sensor, a light guide, and a light controller. The light guide has a pair of opposite ends and is optically-coupled to the lamp and the light sensor at one of the ends. The light guide is configured to convey light emitted from the lamp to the other end of the light guide, and from that other end to the light sensor. The light controller is coupled to the lamp and the light sensor and is configured to flash the lamp and to determine the intensity of light at that other end of the light guide, via the light guide and the light sensor, during an interval between the flashes.

A magnetorheological damper device is provided having a high-bandwidth and high-control ratio, which enhances the performance of the damper. The damper generally includes a cylindrically shaped housing; a magnetorheological fluid disposed in the cylindrically shaped housing; a piston assembly disposed within the cylindrically shaped housing in sliding engagement with the cylindrically shaped housing defining a first chamber. The first chamber is in communication with a second chamber, through a magnetorheological valve assembly which comprises of a plurality of cylindrically shaped fluid passageways extending from the first chamber to the second chamber, and an electromagnet; and a power supply in electrical communication with the electromagnet.
