摘要:
The present disclosure provides devices, systems and methods for sequencing nucleic acid molecules. Nucleic acid molecules can be sequenced with a high accuracy (e.g., greater than 97% in a single pass) using a chip comprising an array of independently addressable nanopore sensors at a density of at least about 500 sites per 1 mm2. An individual nanopore sensor can include a nanopore in a membrane that is adjacent or in proximity to a sensing electrode.

A system that provides a cryptographic unit that generates secret keys that are not directly accessible to software executed by a controller. The cryptographic unit can include a restrictor device, a finite state machine, a random number generator communicatively and a memory. The memory stores values generated by the random number generator. The restrictor device and the finite state machine include hardware logic that restricts access or changes to the contents of the memory.

A video and audio compression and decompression system includes a reconfigurable compact camera communicating with a computer system to permit the camera to execute one of several types of compression modules. The camera includes first and second types of memory. The first type of memory is made of smaller ROM-type memory cells and is used for storing computer-executable video-data-compression subprograms. The second type of memory is made of larger RAM-type memory cells and stores the compression program. A download circuit on the camera is configured to receive transmitted data representing the data compression program and to store the transmitted data in the second memory. A selection is made of the stored subprograms corresponding to the data representing the compression program. An image reader including a data generation circuit captures the external image and generates data representing the image. A processor executes the data representing the computer-executable program and the selected ones of the stored subprograms to generate compressed data, and the compressed data is transmitted from the camera.

Devices and methods for securely upgrading devices, such as field upgradeable units, are disclosed. In response to receiving an update object, a device may determine whether a predefined location of memory includes a predetermined value. Based on the value in the predefined location, the device may store the received update object in a verification portion of the memory. After verifying the authenticity of the update object, the device may copy the update object from the verification portion of the memory to an inactive portion. The inactive portion of the memory can be swapped with an active portion of the memory, such that the inactive portion becomes active.

A videoconferencing system uses a modular terminal that includes a conventional digital still camera coupled to the input port of the videocommunicator, such as a set top box. There are various features provided by this arrangement, including using the digital still camera to present video information to the videocommunicator with a split screen image representing the still image, a receiver arrangement permitting the digital still camera to fit securely and adjacent to the videocommunicator, and pan/tilt/zoom camera features provided electronically.

An arrangement which includes a telephone and an interface unit, which interfaces the telephone to both a standard switched telephone communications network and an Internet communications network, is disclosed. The interface unit includes an input coupled to the telephone to receive audio information and two output ports configured to be respectively coupled to the standard switched telephone communications network and the Internet communications network. A processing unit couples the audio information received from the telephone to the first output port when the telephonic communication is to be performed using the standard switched telephone communications network. Alternatively, the processing unit processes the audio information received from the telephone in accordance with standard Internet transfer protocols and couples the processed audio information to the second output port when the telephonic communication is to be performed using the Internet communications network and the standard protocols.

The present invention provides a method and interface for browsing the internet using a telephone circuit having keys for generating DTMF codes. The interface includes a memory and a processor and is coupled to the telephone circuit and display. The interface receives a first DTMF code requesting access to the internet and, in response to the first DTMF code, loads a Web browser in its memory. The interface then receives a second DTMF code from the telephone circuit and converts the second DTMF code into a Web browser command using an interpretation protocol. The Web browser command is then executed using the interface, thereby enabling a user to access the internet via manual operation of the keys of the telephone circuit.
