Abstract: A method for tracking and positioning a magnetic catheter and a structure of a magnetic catheter are disclosed for facilitating tracking and positioning of catheters in human bodies without using electromagnetic induction as conventionally used. When electromagnetic induction and remote magnetic control are used together, their respective magnetic fields may mutually interfer, increasing the risk of operational errors of the magnetic catheters they are working on. The disclosed magnetic catheter has an elastic unit. While the magnetic catheter bends, inductance variation caused by elastic deformation of the elastic unit is measured for calculating an actual bending angle of the magnetic catheter. Then the motion of the magnetic catheter can be amended accordingly. By using calculation instead of electromagnetic tracking, mutual interference between different magnetic fields can be prevented.

Abstract: A method for controlling a magnetic catheter by using a magnetic-field-generated magnetic annulus is disclosed. The magnetic catheter has a free end provided with a magnetic member. A resultant magnetic field between at least two magnets generates a magnetic annulus. The magnetic catheter is placed into the magnetic annulus, so that the magnetic member is affected by the magnetic force from the magnetic annulus to guide the magnetic catheter to perform a preset motion. The magnetic catheter has a flexible front section, so that the flexible section can perform a bending motion when led by the magnetic member. The resultant magnetic field is generated by arranging the two magnets with their like poles facing each other, so that the magnetic member is thrust when entering the magnetic annulus. This facilitates the bending motion of the flexible section.

Abstract: A method of operating an endoscope by changing a magnetic field and controlling a feeding and a rotation synchronously comprises steps of: providing an endoscope, the endoscope including a magnetic section formed on a front end thereof, the magnetic section having a multi-section bending portion and a magnetic element; and setting a target position in a space. The method of operating the endoscope further comprises steps of: exerting a magnetic field on the magnetic element of the magnetic section, any one of a size, a direction, and a position of the magnetic field is allowed to be changed after exerting the magnetic field on the magnetic element of the magnetic section so that the magnetic element is guided by the magnetic field; and controlling the endoscope to feed or/and rotate based on the target position and a bendable direction of the multi-section bending portion.

Abstract: A wireless intraocular pressure monitoring device includes reflecting and detecting modules. The reflecting module includes a soft contact lens having a curvature corresponding to that of a cornea while worn. A metal layer is embedded in and deformable with the soft contact lens. The detecting module includes two waveguides, an oscillator, and a converting unit. The oscillator is operable to generate oscillation signals having a frequency dependent on an equivalent impedance of the waveguides such that the equivalent impedance corresponds to intraocular pressure. The converting unit is operable for receiving and converting the oscillation signals into an output signal corresponding to the intraocular pressure.

Abstract: A highly sensitive inertial mouse is in particular to one using an MEMS(Micro-Electrical-Mechanical System)inertial sensitive principle; the mouse uses MEMS inertial sensitive principle including a two-dimensional or three-dimensional inertial sensors or accelerometers and with the use of signal processing methods such as collecting of data, noise cancellation, setting of threshold of dead zone, tracking of baseline, calculation of displacement and adjustment of sensitivity and so on, enable the MEMS sensor acting as the manufacturing component of a computer mouse; furthermore, the present invention is not only light and energy saving, but also obviates the drawbacks of high power consumption of optics mice or easy-dirt collection of roller mice. Moreover, with the increase in sensitivity, the bottleneck in the manufacturing of inertial mouse is overcome such that the functions of MEMS inertial mouse is very stable and reliable and can be easily used.

Abstract: A full range of alphanumeric characters is obtained with two different modes upon a twelve key telephone keypad. Numerics are obtained with single keystrokes in one mode and English alphabetics obtained with single and paired keystrokes in another mode. Memory is provided in which a plurality of telephone numbers can be stored, organized, identified and retrieved by a combination of alphanumeric characters including names and abbreviations. A visual display facilitates storing and retrieval of any telephone number. Alphanumeric messages can be transmitted to, and received from, other remote telephonic devices. Any language is encompassed and use of two languages on one keypad is facilitated. Characters in one language such as English are obtained as above in one mode and characters of another language possessing considerably more characters, e.g.

Abstract: A keyboard having fewer keys than the characters available utilizes linked sequences of keystrokes in generation of some characters. Other characters may be produced with one keystroke. The difference between linked keystrokes and independent keystrokes both made in sequence is determined by either the length of the interval between keystrokes or use of a delimiting key. A threshold level for the interval between keystrokes which decides whether two sequential keystrokes are linked or not may be set by the user or may be automatically determined with the use of an adaptive predictive algorithm. It is generally suggested that pairs of keys be linked, particularly adjacent pairs of keys in a fixed configuration, and that the characters generated by either a single keystroke of a given key or the characters generated by two linked keystrokes be represented upon the keyboard in a disposition which facilitates intuitive learning of the keyboard.

Abstract: A solar panel is operably connected to a power capacitor and associated circuitry which includes at least one diode for ensuring correct current flow direction. The power capacitor is inside a cartridge which is has exterior electrical contacts and overall dimensions enabling it to fit into the space intended for and replace at least one conventional battery. The exterior contacts, in conjunction with the power capacitor and associated electrical circuitry, enable provision of direct current (DC) electrical power of appropriate voltage and amperage to various electronic devices: cellular telephones, personal digital assistants (PDAs), compact disc (CD) and digital video disc (DVD) players, infrared and radio remote controllers, and other low power consumption devices including radios, alarms and calculators, etc.

Abstract: An infrared remote controller is provided with power by a capacitor supplied by an electrical power supply preferably including a photovoltaic panel which converts light into electricity. A main switch closes the circuit between the power capacitor and the controller. An interface circuit having at least one diode, but preferably at least two in parallel to minimize resistance, connects the power supply to the capacitor. This interface circuit may also include a power level testing circuit, preferably one utilizing a light emitting diode (LED). A rechargeable battery may be included in the power source for greater power reserve. A voltage reference or voltage regulator is recommended between the capacitor and the infrared remote controller. The sizing of the capacitor in accordance with the consumption requirements of an infrared remote controller and the operating voltage enables a very simple circuit overall.
