摘要:
In third generation mobile communications networks, e.g. CDMA systems, a mobile station intending to access a base station transmits a request for access to a base station and waits for a response in the form of an indicator signal. Both detecting a signal as an acknowledgement message without one being sent from the base station and failing to detect such an acknowledgement message can give rise to noise and interference in the whole cell. The invention provides a method and a user equipment for determining the received signal strength in an access slot in a downlink channel and for asserting whether detection of an indicator signal from the base station in the access slot in the downlink channel is reliable. Hereby, a more secure reception of indicator signals can be obtained, which leads to reduced interference and noise in the whole cell.

The present invention relates to the technical field of biology, and in particular relates to a lytic composition and an application thereof, a kit, a method for preparing nucleic acid by utilizing the lytic composition, and a nucleic acid analysis method. A lytic product obtained in the present invention can be directly used for the nucleic acid analysis method without purifying the nucleic acid. According to the lytic composition disclosed by the present invention, multiple biological tissues and cells are lysed so as to release the nucleic acid of the cells into a solution, the nucleic acid in a whole-cell lysing and mixing state directly serves as a template without using a conventional nucleic acid separation and purification process after termination of the reaction, and nucleic acid amplification analysis is guided. For example, nucleic acid amplification is performed by a real-time fluorescence qPCR, etc.

A method for presenting radiographic images of a subject obtains, from the same radiographic image capture, at least a first image and a second image, wherein the at least first and second images differ in presentation. The method associates the at least first and second images as companion images according to one or more entered instructions. There is displayed at least a first executable data link that relates to a first storage location of the first image and a second executable data link that relates to a second storage location of the second image. In response to an operator selection of either of or both of the first and second executable data links, the method displays either the corresponding first or second image, or both companion images.

There is provided a computer-implemented method for transmitting data over a wireless network using white spaces. A first white space transmission channel is determined for communicating with mobile client devices. Wireless communication takes place with the mobile client devices over the first white space transmission channel. If the first white space transmission channel becomes unavailable to one of the mobile client devices because of the presence of a primary user on the first white space transmission channel, a different white space transmission channel is determined for communicating with the mobile client device that is affected. The first white space transmission channel may become unavailable to the affected mobile client device, for example, because a primary user begins using the first white space transmission channel in proximity to the affected device. The primary user may be a wireless microphone. Thereafter, communication with the affected wireless device takes place on the different white space transmission channel, while unaffected devices continue to communicate on the first white space transmission channel. Also provided are an exemplary wireless base station and an exemplary mobile client device.

A system for playing digital television. A server presets a video on demand (VOD) protocol specification, and transmits, according to the VOD protocol specification, a VOD service list and additional information to a digital television receiving terminal. The receiving terminal presets the VOD protocol specification, and stores, according the VOD protocol specification, the received VOD service list and additional information in an on-demand program database. Relative programs in the on-demand program database are matched according to a matching mark input by a user and displayed. In response to a program on-demand request of the user, the receiving terminal obtains the television program from the server and plays that program.

A method for multimedia broadcast and multicast service, MBMS, notification indicator detection from multiple MBMS notification-indication channel, MICH, frames in a User Equipment operating in a Wideband Code Division Multiple Access system is disclosed. The method comprises determining a desired number of MICH frames; upon connection with a NodeB, receiving an available number of MICH frames within a modification period; decoding notification indications of the received MICH frames; determining a majority value being the number of notification indications having a most frequent value of the decoded notification indications; and if a ratio between the majority value and the desired number of MICH frames is above a threshold value, determining the correct notification indicator to be the most frequent value, or if the ratio between the majority value and the desired number of MICH frames is less than the threshold value, connecting to the NodeB; receiving further MICH frames; and decoding notification indications of the received MICH frames such that the correct notification indicator is achieved. A computer program and a User Equipment apparatus are also disclosed.

A method for acquiring a sequence of fluoroscopic images of a subject acquires and displays a basis image from a fluoroscopic imaging system. A region of interest is defined within the displayed basis image in response to one or more viewer instructions entered on the displayed basis image. One or more signals are generated that adjust the position of one or more components of the fluoroscopic imaging system according to the one or more viewer instructions.

The present invention provides novel algorithms for designing oligonucleotides that do not substantially hybridize to a small group of unwanted transcripts, while hybridizing to most other transcripts. Such oligonucleotides are particularly useful as primers for reverse transcription. The invention also provides compositions containing oligonucleotides that do not substantially hybridize to a small group of unwanted transcripts, while hybridizing to most other transcripts.
摘要:
A method for aligning a radiation source with a portable image receiver in a radiographic imaging system generates a magnetic field with a predetermined field pattern and with a time-varying vector direction at a predetermined frequency from an emitter apparatus that is coupled to the radiation source, wherein the generated magnetic field further comprises a synchronization signal. Sensed signals from the magnetic field are obtained from a sensing apparatus that is coupled to the image receiver, wherein the sensing apparatus comprises three or more sensor elements, wherein at least two of the sensor elements are arranged at different angles relative to each other and are disposed outside the imaging area of the image receiver. An output signal is indicative of an alignment adjustment according to the amplitude and phase of the obtained sensed signals relative to the synchronization signal.
