  • Diffusion-controlled dosage form and method of fabrication including three dimensional printing
    Publication number: 20120177696
    Abstract: The invention includes a core-and-shell dosage form or unit in which the core contains API and in which the shell substantially governs the release such as by controlling diffusion of API through the shell. The shell may comprise a release-blocking polymer, and particles of a release-regulating polymer. The shell may be substantially impervious but the release-regulating polymer may become suitable to allow diffusion through it when activated. The core may include a buffer region between the shell and the API-containing portion of the core. The dosage form may include multiple units. The dosage form of the invention is capable of providing a release profile whose time scale can be adjusted by adjusting powder composition, and which may be approximately zero-order release. The invention further includes methods of manufacturing such a dosage form, such as three-dimensional printing.

  • Audio output apparatus capable of suppressing pop noise
    Patent number: 8036399
    Abstract: An audio output apparatus includes: an audio codec outputting an analog audio signal corresponding to a digital audio signal from a system controller; a switch unit having a first end coupled to the audio codec through a capacitor, and a grounded second end; and a switch controller triggered by a trigger signal to output a control signal to a control end of the switch unit such that the switch unit couples the capacitor to ground in response to the control signal. The trigger signal is generated by one of the system controller, the audio codec, and a power circuit supplying electric power to the system controller, the audio codec and the switch controller upon occurrence of a condition associated with pop noise, and is outputted to the switch controller before the pop noise is generated, such that the pop noise is conducted to ground via the switch unit.

  • Method and form of a drug delivery device, such as encapsulating a toxic core within a non-toxic region in an oral dosage form
    Patent number: 7875290
    Abstract: A drug delivery device such as an oral dosage form (ODF) with a toxic or potent core encapsulated by a non-toxic region. The non-toxic region may be a region including multiple layers, coatings, shells, and combinations thereof, which provides protection to and isolation from the toxic or potent core. The drug in the toxic or potent core is incorporated into the dosage form via, for example, three-dimensional printing, as a solution, solubilization or suspension of solid particles in liquid, rather than by the more conventional handling and compressing of dry powder. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. Wet dispensing of the toxic or potent drug further provides greater bioavailability of the drug to the patient.

    Abstract: An apparatus and method for detecting the oscillation amplitude of a bonding tool includes a sensing unit disposed adjacent to and at a distance from the bonding tool. The sensing unit includes a pair of electrodes, a piezoelectric sensing layer located between the pair of electrodes, and a membrane associated with the piezoelectric sensing layer. The piezoelectric sensing layer becomes sensitive to ultrasonic vibrations and generates electrical voltage signals after being activated by a poling process. An optional pre-amplifier is used to amplify the signals generated from the sensing unit, and an oscilloscope is used to further process the signals.

    Abstract: A method of showing a TV channel menu includes the following steps. Firstly, an audience evaluation data including a first audience rating of a first TV program and a second audience rating of a second TV program is received. Then, the TV channel menu is opened. Afterwards, the TV channel menu including a first displaying block corresponding to the first TV program and a second displaying block corresponding to the second TV program is shown on a screen. If the first audience rating is higher than the second audience rating, the first display block has a higher conspicuous degree than the second displaying block.
