Abstract:
A motor drive for conditioning power to be delivered to a load includes a current feedback circuit that monitors current being fed to a transformer connected between the motor drive and the load. Based on the total current input to the transformer, a controller adjusts the V/Hz profile along which the motor drive operates. In this regard, the motor drive operates according to a V/Hz profile during start-up that prevents transformer saturation.
Abstract:
A lamp structure with a signal transmission alert includes a lamp seat and a transparent shade, wherein a concave space is located at a bottom of the lamp seat within which located a light and heat source. The light and heat source is connected to a personal computer via a USB signal line. A liquid containing transparent or reflective floating objects or other dynamic devices with changeable colors is filled in the transparent shade. The transparent shade is connected to the concave space in the lamp seat. The light and heat source can be driven with a power provided from the USB device to generate a heat during transmitting computer data, so as to form convection in the liquid in the transparent shade. The floating objects constituting a visual effect of exotic, dynamic, and versatile style is able to transmit along with the transmission of computer data.
Abstract:
A lamp structure with a function of candlestick primarily includes a lamp seat, a light source located at a top of the lamp seat, and both a battery chamber provides both a DC power source and an AC power source, enabling the provision of power source to the light source through a conventional AC, DC power source. A liquid containing transparent or reflective floating objects is filled in the transparent shade which is covered on a periphery at a top of the light source. A candlestick in a dish shape is located at a top of the transparent shade, for holding a candle. A visual effect of dynamic change is created to the floating objects by a projection of light into the transparent shade from the light source, and by heating up the liquid in the transparent shade from the light source, thereby increasing the interest in application.
Abstract:
A pipe clamp assembly that includes a v-band clamp and a v-ring. The v-band clamp includes a band that carries a T-bolt tightening mechanism and a v-insert. The v-insert has an inwardly facing concave surface that fits over radially projecting flanges on the ends of the pipes or other tubular bodies to be joined. The v-ring is formed from sheet metal and has a convex profile and fits between the flanges so that the flanges can be tightly compressed between the v-insert and v-ring during tightening of the clamp. The angle of the walls defining the convex profile of the v-ring can be greater than that of the v-insert so that the v-ring provides some outward springing force on the flanges during tightening of the clamp. The v-ring can have an indexing feature and one or more clips for pre-attachment. A method of making the v-ring is also provided.
Abstract:
A package of a semiconductor device with a flexible wiring substrate and a method thereof are provided. The package of the semiconductor device includes a semiconductor substrate with at least one pad on a surface thereof, a bump bonded to the pad, an adhesive layer on the bump, and a flexible wiring substrate having at least one contact section being electrically connected with the bump by the adhesive layer. The present invention makes the flexible wiring substrate directly conductively attached onto the semiconductor substrate. The package size is shrunk and the cost down can be obtained.
Abstract:
A system, method, and apparatus are provided for copying a virtual volume to multiple physical volumes within a virtual tape system. The virtual tape system may include a virtual tape server (VTS), a library manager, and a plurality of tape drive units into which cartridges may be individually mounted. The virtual tape system stores virtual volumes, each of which represents a physical volume, although one or more virtual volumes are actually stored on a real physical volume. The library manager contains a volume database with a plurality of constructs and associated storage management actions. The constructs are received from a host computer connected to the VTS, but the storage management actions may be entered directly into the library manager, independently of the host. The library manager reads the management action associated with one or more constructs of a virtual volume and, along with the VTS, determines whether multiple physical copies of the virtual volume are to be made.
Abstract:
A portable electronic device is disclosed. The portable electronic device includes a housing. The portable electronic device also includes computing electronics that are supported by the housing. The computing electronics include a processor, a display controller coupled to the processor, and memory coupled to the processor. The portable electronic device disclosed also includes an expandable display coupled with a display controller. The expandable display is expandable from a first size to a second size. The first size is different than the second size. A sensor is coupled to the processor. The sensor is configured to provide a signal representative of the size of the display.
