46results about How to "Reduce manipulation" patented technology

The embodiments relate to tamper protection of a field device. The method includes: checking whether manipulation of the field device has taken place; outputting a non-manipulation certificate in case a negative inspection result is determined; transferring the non-manipulation certificate; a registration device checking the non-manipulation certificate; determining an active status of the field device in case the non-manipulation certificate is valid; checking the field device by querying the status of the field device; transferring field device data to the monitoring device; and accepting the field device data if the field device has an active status. The invention further relates to a monitoring system for a field device and a use.

A portable hand-held endoscopy system adapted for interchangeable use with a variety of endoscopes. The system includes an endoscope having a first end and a second end, the first end having an eyepiece and the second end having a viewing end, the endoscope further having a coupler for coupling to a light source; and a battery operated unitary digital camera having an optical input, viewing screen, digital signal processor, memory with embedded software for processing data from the processor and for displaying an image on the viewing screen, and a coupler having a first end and a second end, wherein the first end includes a connector for removably connecting to the eyepiece, and the second end is coupled to the optical input of the digital camera. The video display is rotatable and pivotable about several different axes of rotation and a pivot point spaced distally from the main camera body. An ergonomic camera housing is provided, including a bulbous gripping region and two opposing forefinger accepting regions, facilitating a trigger-like grip and use of the camera by a physician. Redundant controls for moving video and still image capture facilitate ease of use by the physician as the camera and associated endoscope are held in a variety of orientations.

Copy protection is provided at a mass storage device provided in or connected to a decoder for receiving digital transmissions of audio and video program material by virtual scrambling of blocks of data. Non-sequential storage locations for blocks of data are defined in accordance with a key and the file allocation table is encrypted and stored. Thus blocks of data remain intact and need not be decrypted upon playback, reducing processing time, while the program is effectively protected from reassembly without decryption of the file allocation table. The key(s) may be maintained internally within the decoder and need not be shared, thus avoiding a need for user identification and/or authentication. Software for encryption, including keys may be downloaded to the decoder through the same transmission link used for transmission of data files that may be encrypted in response to control signals or flags transmitted with data files to be protected.

A computer input device includes a housing, a move tracking module, and a light pervious plate. The move tracking module is disposed in the housing, and emits a sensing light. The light pervious plate is movably disposed between the housing and the move tracking module, and may be moved between a first position and a second position relatively to the move tracking module. In this manner, the sensing light selectively penetrates the light pervious plate and is emits out of the housing, or is directly emits out of the housing, so that the computer input device correspondingly executes a touch mode or a mouse mode.

The present invention relates to protein purification. More particularly, a method for directly recovering an objective protein from a protein composition and purifying a protein with a desired quality in a rapid and efficient manner is provided. Further, a rapid purification method capable of efficiently removing impurities included in the protein composition is provided. Therefore, compared to the conventional purification methods, quality and yield of the protein can be remarkably improved.

A process for purifying cyclic lipopeptide compounds or salts thereof comprising the steps of: (1) charging a crude compound of Formula I onto a macroporous adsorption resin; (2) washing the macroporous adsorption resin using water, an organic solvent or a mixed solution of an organic solvent and water as a washing liquid; and (3) eluting the compound of Formula I from the macroporous adsorption resin using water, an organic solvent or a mixed solution of an organic solvent and water as an eluent. The purification method has the advantages of using a small amount of organic solvents, using no silica gel, and causing little damage to the environment; the purity of the collected compound of formula I is also improved as compared with the methods previously disclosed.

Disclosed herein, inter alia, are substrates, kits, and efficient methods of preparing and sequencing two or more regions of a double-stranded polynucleotide.

A clutch-manipulation assist mechanism of a vehicle clutch mechanism is capable of disconnecting power of an engine and is provided to a power transmission path which transmits the power of the engine to a rear wheel. The clutch-manipulation assist mechanism includes a push rod member which is arranged near the clutch mechanism and which is movable in the axial direction interlockingly with a power cutoff of the clutch mechanism due to the manipulation of a clutch lever by a rider. An axial movement of the push rod member is assisted by an actuator in response to a detection of the clutch lever manipulation by the rider using a stroke sensor, thus reducing a manipulation force of the clutch lever. A detection lug of the stroke sensor detects a movement quantity of a shaft end of the push rod member.
