Abstract:
A distributed amplifier is disclosed herein, which includes a signal amplification unit amplifying a RF input signal fed into the RF signal, a first biasing circuit providing a direct current (DC) bias signal, a second biasing circuit providing a DC bias signal, the variable terminal resistance providing an adjustable resistance, a RF signal input terminal provided for input of the RF input signal and a RF signal output terminal for output of a RF output signal. The output RF signal from the distributed amplifier is obtained from a gained version of the input RF signal. Since a load mismatch issue is compensated, a gain flatness issue is considerably improved and thus a gain-adjustable range is increased with respect to the distributed amplifier.
Abstract:
A projection apparatus having a single reflective light valve is provided. The projection apparatus includes a non-telecentric illumination system, a movable projection lens and a reflective light valve. The non-telecentric illumination system includes a light source and a lens. The light source is suitable for providing a light beam and the lens is disposed on the transmission path of the light beam. The movable projection lens is disposed behind the lens on the transmission path of the light beam for projecting an image. An image projected from the projection apparatus has an offset between 100%˜150%. The reflective light valve is disposed between the lens and the movable projection lens on the transmission path of the light beam. The reflective light valve has rows of horizontally arranged pixels.
Abstract:
A hybrid gas inflator utilizes a combustion chamber to generate a gas of hot jet. The gas pushes a piston downward and flows through a hole of the piston along its axis so as to break a pressure-resisting disc. The gas is then injected into a high-pressure gas container to heat up another gas therein. The hybrid gas gets expanded and is ejected through a plurality of exhaust outlets. This hybrid gas inflator can produce larger gas volume and therefore can reduce the size and weight of an inflator. Further, the impurities in the hybrid gas are congealed fast after two stages of pressure drop and can be removed easily by a filter.
Abstract:
A storage virtualization computer system. The storage virtualization computer system comprises a host entity for issuing an IO request, a storage virtualization controller coupled to the host entity for executing IO operations in response to the IO request, and a at least one physical storage device, each coupled to the storage virtualization controller through a point-to-point serial-signal interconnect, for providing storage to the storage virtualization computer system through the storage virtualization controller. As an example, the point-to-point serial-signal interconnect can be a Serial ATA IO device interconnect.
Abstract:
A cleaning device includes a first cleaning member attached to a lower end of an elongated rod, and a second cleaning member mounted slidably on the first cleaning member. The second cleaning member is slidable in a transverse direction relative to the rod between an extended position, in which the second cleaning member is moved away from a free end of the first cleaning member, and a retracted position, in which the second cleaning member is moved toward the free end of the first cleaning member.
Abstract:
A DC/DC charge and supply converting module has a function of constant-current charging an electrical appliance, and a function of supplying constant voltage power to an electrical appliance. The converting module includes a DC/DC converter and a charge module connected with an input end of the DC/DC converter. The charge module includes a comparator, a constant current source connected with a first input end of the comparator, and a bleeder circuit connected to a second input end of the comparator. The comparator is used for controlling an output voltage of the DC/DC converter to remain constant. The constant current source provides a constant current to the corresponding input end of the comparator and allows the DC/DC converter to output a constant current for the purpose of charge.

Abstract:
A vibration ring includes a vibration module and a latex ring. The vibration module is provided with at least a battery, a circuit board and a vibration motor that are connected electrically in a spherical shell, along with a switch that is exposed out of the shell. The latex ring includes an annular wearing part that is processed with latex, and a spherical vibration part that encloses the shell of the vibration module. The spherical vibration part and the enclosed vibration module act onto a female's clitoris without pressing on other parts of the body, so as to increase the comfortableness in wearing the vibration ring and form a better exciting effect in vibration.
Abstract:
Techniques are disclosed for virtualizing internet protocol (IP) addresses in terminal server sessions. A client component comprises a layer service provider (LSP) and a name service provider (NSP) that intercept a socket call to associate a port with a socket for a terminal server session. The client component queries a server component for a virtual IP address, and the server component determines whether the terminal server session can use a virtual IP address. Where the session can use a virtual IP address, the server returns a virtual IP address and the client component binds the socket call to the virtual IP address. Where the session cannot use a virtual IP address, the server returns an indication of that, and the client component acts as a proxy for that socket call and any future calls for that socket.
Abstract:
A system for producing microbeads includes a microfluidic device defining a supply channel and a shearing channel, a microbead precursor material disposed in the supply channel, a carrier fluid disposed in the shearing channel, and a pressure distribution system fluidly connected to each of the supply channel and the shearing channel to control at least relative pressures of the microbead precursor material and the carrier fluid. The supply channel includes a check valve adapted to be subjected to a bias pressure that is sufficient to close the check valve to flow of microbead precursor material when a supply pressure of the microbead precursor material is below a threshold pressure and is open to flow of the microbead precursor material when the supply pressure of the microbead precursor material is greater than the threshold pressure. An end of the supply channel opens into the shearing channel such that the microbead precursor material is sheared into droplets by the carrier fluid flowing through the shearing channel. A pressure of the carrier fluid is less than the bias pressure. The microbead precursor material and the carrier fluid are substantially immiscible.
