Abstract:
An automatic switching device for the power source input range of a personal computer monitor is installed within the switchmode power source circuit of the monitor and includes a comparator and a relay arranged so that, irrespective of whether the power source is at a 110V or 220V voltage level, the rectifying circuit of the switchmode power source circuit is automatically switched to a voltage doubler circuit or a bridge rectifier circuit as appropriate for reducing power losses and saving energy.
Abstract:
A polarized plate includes a polarized layer, a first optical film located on a upper side of the polarized layer and a second optical film located on a lower side of the polarized layer. At least one of the first and second optical films is made from Polymethyl Methacrylate (PMMA). The optical films are formed by dispensing a mixed solution on a substrate, then bonding to the polarized layer and processed through a heat treatment. The optical films may also be formed by dispensing the mixed solution on the surface of the polarized layer and processed through a heat treatment.
Abstract:
A records management system classifies records according to a file plan. Record are declared, and then classified. Some records have in initially indeterminate classification and classification is deferred, either by request or due to a lack of sufficient information to classify the record according to the file plan. Unclassified records are placed into a temporary container. At some time while in the temporary container a classification event occurs with a given record which allows the records management system to classify the record and place it into a container corresponding to its classification.
Abstract:
A computer monitor power supply system includes a comparator, a relay, and an inductor connected in series between the AC input and a flyback transformer circuit. The inductor includes two windings which are automatically switched between a parallel connection and a series connection upon switching between a 110 V and 220 V power input so as to reduce the amount of low frequency harmonics.

Abstract:
The present invention discloses a PCI-Express multimode expansion card comprising a PCI-Express interface port for insertion into a PCI-Express slot of a motherboard, a PCI-Express expansion port, a USB expansion port, and a jumper circuit connecting the PCI-Express interface port and the two expansion ports. The PCI-Express expansion port provides expandability by allowing the attachment of a PCI-Express interfaced peripheral device, and the USB expansion port provides expandability by allowing the attachment of a USB-interfaced peripheral device. As such, a single PCI-Express multimode expansion card inserted into a PCI-Express slot configured on the motherboard can be used to attach two peripheral devices with different interface, thereby achieving the function of multimode expansion.
Abstract:
An extended range received signal strength indicator module includes input lines connected to a variable gain amplifier, which passes the amplified RF signal to a polyphase, which in turn passes the filtered signal to a series of RSSI stages. Each RSSI stage includes a log amplifier and outputs an amplified current to a current summer as well as to the next RSSI stage in the series. The current summer outputs the sum of the received currents to RSSI_OUT. An additional frequency filter and RSSI stage with inputs connected to the input lines before the variable gain amplifier that outputs the modified current to the current summer is also included. A control circuit switches the additional RSSI stage on or off as determined by a detection circuit that monitors the value of RSSI_OUT.
Abstract:
A method for fabricating optical compensation films includes providing PAR polyarylate; dissolving the PAR polyarylate in an solvent to obtain a polyarylate solution; applying the polyarylate solution on a substrate; and substantially removing the solvent from the polyarylate solution under a predetermined temperature to form an optical compensation film having a thickness of 1 μm to 20 μm. The optical compensation film is optically anisotropic and suitable for use in photoelectric flat displays.
