Abstract:
A computer output system having a first full screen bitmapped memory, a second full screen bitmapped memory, logic circuitry for providing input signals for writing information to be displayed by an output device to each position of the first memory, logic circuitry for storing in the second memory the positions of each position of the first memory to be written to the output device, and logic circuitry for comparing the signal stored at each position of the first memory and the signal stored at the same position of the second memory to determine whether information at the position is to be written to the output device.
Abstract:
A humidifier heater base assembly has a heater plate with a thermally conductive portion and a perimeter portion around a perimeter of the heater plate. A resilient member has an inner part attached to the perimeter portion and an outer part adapted to provide a resilient perimeter flange around at least part and preferably the whole of the perimeter portion. The resilient member fixes the heater base to the humidifier by the resilient perimeter flange such that the heater plate and the inner part can move relative to the humidifier in a direction substantially transverse to the general plane of the heater plate. At least a portion of the resilient perimeter flange remains stationary relative to the humidifier.
Abstract:
A connector for connecting a coaxial cable and a circuit board is disclosed. The connector includes a main body, a first holding portion, a second holding portion and a fixing structure. The first holding portion extends from a first end portion of the main body for holding a first insulation layer of the coaxial cable. The second holding portion extends from the main body in a position located between a second end portion opposite to the first end portion and the first holding portion for holding a braid layer of the coaxial cable. The fixing structure extends from the second end portion of the main body in a direction away from the second holding portion for disposing through at least one hole on the circuit board, so as to fix the coaxial cable on the circuit board.
Abstract:
A nanoplasmonic resonator (NPR) comprising a metallic nanodisk with alternating shielding layer(s), having a tagged biomolecule conjugated or tethered to the surface of the nanoplasmonic resonator for highly sensitive measurement of enzymatic activity. NPRs enhance Raman signals in a highly reproducible manner, enabling fast detection of protease and enzyme activity, such as Prostate Specific Antigen (paPSA), in real-time, at picomolar sensitivity levels. Experiments on extracellular fluid (ECF) from paPSA-positive cells demonstrate specific detection in a complex bio-fluid background in real-time single-step detection in very small sample volumes.
Abstract:
A rotary encoder and an optical wheel for the rotary encoder are provided. The rotary encoder further includes a light source module, a code plate and an optical sensor module. The light source module is coupled with the code plate. The optical wheel is rotary, and has imaging elements arranged annularly; at least one of the imaging elements is coupled with the code plate. The optical sensor module is coupled with at least one of the imaging elements. The light source module emits lights to the code plate, and the lights passing through the code plate forms an image which is then transmitted to the optical sensor module via the imaging element. When the optical wheel rotates, the image moves accordingly. The optical sensor module senses that the image moves. A method for generating a zeroing signal of a rotary encoder and a liner encoder are also provided.
Abstract:
A method for ordering a disordered alloy includes: simultaneously ion bombarding and annealing a disordered alloy to transform the disordered alloy from a disordered crystalline state to an ordered crystalline state. A method for making a perpendicular magnetic recording medium which includes an ordered alloy layer is also disclosed.
Abstract:
A breathing assistance unit for providing pressurized heated humidified air at to a user is configured to increase user compliance. The breathing assistance unit comprises means for generating positive emotional and cognitive states of a user about the therapy.
Abstract:
An apparatus for demodulating a digital video signal applied to a receiving end of an Orthogonal Frequency-Division Multiplexing (OFDM) communication system is provided. The apparatus receives a plurality of OFDM symbols, and stores a plurality of data sequences in an external memory. The apparatus includes a de-interleaver, that de-interleaves the data sequences to generate a plurality of de-interleaved data sequences; a decoder, coupled to the de-interleaver, that generates a plurality of data streams according to the de-interleaved data sequences; a reconstruction apparatus, coupled to the decoder, that reconstructs the data streams into a transport stream; and a memory interface unit, coupled to the external memory, that accesses the data sequences and the data streams from the external memory. The external memory includes a de-interleaving buffer that stores the data sequence, and a data reconstructing buffer that stores the data streams.
