Abstract: An armlet-type alarm includes a main body having a control circuit and a buzzer mounted therein, and a length-wise adjustable fastening band connected to the main body. The main body is provided at a top with a large-sized alarm push button assembly having a light-emitting device located therein, and a light-up switch for actuating the light-emitting device to emit light intermittently. One side of the main body includes a sound box, which uses a user's arm as one sidewall thereof and has a plurality of sound apertures provided therein. The armlet-type alarm may emits an intermittent warning light if so desired, and may be caused to emit a loud sound in an emergency simply by clapping the alarm push button assembly to actuate the buzzer inside the main body of the alarm.

Abstract: Water-soluble, photosensitive, optically variable (POV) inks exhibit improved OCR readability due to improved infrared absorption properties. The inks can produce images that can be viewed with both visible and ultraviolet light to have physically coincident positive and negative images. The new inks contain at least two types of colorants in addition to the IR absorber and other suitable ingredients. The first colorant comprises a fluorescent dye or pigment emitting light within a characteristic emission band when excited by fluorescent-exciting radiation. The second colorant comprises a carbon black infrared radiation absorbing composition alone or with one or more dyes or pigments having a light absorption band at longer wavelengths than the characteristic emission band of the first colorant or also overlapping the emission wavelength of the first colorant in such a way as to result in a dark color.

Abstract: New photosensitive optically variable inks are capable of printing images having improved resistance to water. The inks produce images which can be viewed with both visible and ultraviolet light to have physically coincident positive and negative images. They contain at least two types of colorants and other suitable ingredients to enable preparation for printing. The first colorant comprises a fluorescent dye emitting light within a characteristic emission band when excited by fluorescent-exciting radiation. The second colorant, which comprises a colloidal pigment alone or with a dye, has a light absorption band at longer wavelengths than the characteristic emission band of the first colorant or overlapping the emission wavelength of the first colorant, effectively to result in a dark color.

Abstract: Certain embodiments include an etching method including providing an etch material, applying a gas mixture including hydrogen, forming a plasma, and etching the etch material. The etch material can include a low-k dielectric material. The gas mixture can include a hydrogen gas, a hydrogen-free fluorocarbon, and a nitrogen gas, and further include one or more of a hydrofluorocarbon gas, an inert gas, and/or a carbon monoxide gas. The hydrogen gas can be a diatomic hydrogen, a hydrocarbon, a silane and/or a fluorine-free hydrogen gas, including H2, CH4, C2H4, NH3, and/or H2O gases. The hydrogen-free fluorocarbon gas can be a CxFy gas (where x?1 and Y?1) and the hydrofluorocarbon gas can be a CxHyFz gas (where x?1, y?1 and z?1). The gas mixture can be free of oxygen. Embodiments can include reduced pressures, reduced hydrogen flow rates and one or more plasma frequencies.

Abstract: An SOC has a processor, an internal high-speed bridge circuit, an internal low-speed bridge circuit, and an expansion port. The expansion port is capable of selectively being connected to an external low-speed bridge circuit for expanding functionality of the internal low-speed bridge circuit.

Abstract: A microphone includes a handgrip portion, a protective sleeve, and a connector interconnecting the handgrip portion and the protective sleeve. The connector includes a terminal seat connected to the handgrip portion and formed with a plurality of terminal passages, a first pivot part connected to the terminal seat, and a second pivot part pivoted to the first pivot part and connected to the protective sleeve so as to permit co-rotatation of the protective sleeve and the second pivot part relative to the handgrip portion.

Abstract: A positioning device for a microphone includes a mounting plate having a connecting plate section mounted detachably and securely on a horizontal mounting portion of a clamp unit, and a holding plate section that extends outwardly from the connecting plate section, that is formed with an elongated slot extending along the length of the holding plate section, and that is connected to the microphone at one side of the elongated slot. An adjuster bolt is disposed at the other side of the elongated slot, extends through the elongated slot, and threadedly engages a base of the microphone so as to permit adjustment of the position of the microphone relative to the clamp unit along the elongated slot.

Abstract: A stand for holding a camera or a microphone, includes a cylindrical tube unit having an inner wall surface defining an axially extending post-receiving chamber to telescopically receive a post therein. A positioning element is fixed on the tube unit. First, second and third support legs have upper portions sleeved on an outer wall surface of the tube unit. The second and third support legs are rotatable relative to the tube unit in such a manner that the second and third support legs can be stacked below the first support leg when the stand is in a storage position and that the first, second and third support legs engage the positioning element and are angularly spaced apart from one another when the stand is disposed at a position of use.

Abstract: A book light includes: a shade having a lamp and an electrical control circuit fixed within the shade, a base for pivotally mounting the shade and the lamp on the base, a clamping device protruding forwardly from the base to be clamped on a book, and a push-button switch resiliently held in the shade normally protruding outwardly beyond the shade, whereby upon closing of the shade on the base, the push-button switch will be retracted into the shade to turn off the lamp as depressed by the base when pivotally folding the shade on the base; and upon opening of the shade from the base, the push-button switch will be automatically protruded outwardly to close the electrical control circuit to power and turn on the lamp for lighting use.

Abstract: A lock and alarm device includes: a lock body held on a window and door rail at a lower position of the door or window for an easier concealment, a vise having two jaw members telescopically mounted in a bottom of the lock body to be firmly tensioned or retained on the rail as driven by a knob for retarding a sliding opening of the window and door, and an alarm mounted on the lock body and operatively actuated for sensitively detecting an unexpected opening of the window and door for enhancing security when the opening of the window or door triggers a touch-on switch of an alarm circuit, or when the vibrations caused by the opening of the window or door actuates a vibration sensor of the alarm circuit.
