  • Publication number: 20120155676
    Abstract: An impedance matched connection is provided between a load and a power source that outputs signals within a predetermined frequency range. A coaxial line has a predetermined characteristic impedance, an inner conductor, an outer conductor, and an insulator between the conductors. Each conductor has a first end electrically connectable to output terminals of the power source. A compensation circuit has an adjustable impedance, a first terminal electrically connected to a second end of the inner conductor and to a first terminal of the load, and a second terminal electrically connected to a second end of the outer conductor and to a second terminal of the load. The compensation circuit is adjustable to attain, for a pulse having a rise time/fall time faster than the rise/fall times associated with the predetermined range of frequencies, a combined impedance and load that is substantially equal to the characteristic impedance of the coaxial line.

  • Patent number: 8195091
    Abstract: A teacher microphone (30) is provided with an infrared (IR) transmitter to signal a connection request to a wireless audio access point (50) using a first IR request inquiry signal (331). In response to this first IR code, the wireless audio access point establishes a first RF communication link (300). After the first RF communication link is established, the teacher microphone conditionally transmits a first IR presence signal (332) to verify that it is still collocated in the local vicinity of the wireless audio access point, such as being in the same room. The wireless audio access point is capable of maintaining a connection with additional portable wireless devices, such as a student microphone (40).

  • Patent number: 8190095
    Abstract: A wireless communication access point is provided with an infrared beacon transmitter to signal a connection request to a portable wireless device, such as a microphone, using an IR room code. In response to this IR room code, the portable wireless device broadcasts a RF inquiry message that is responded to by the wireless communication access point in order to establish a RF communication link. After the RF communication link is established, the wireless communication access point periodically transmits the IR room code to verify that it is still collocated in the local vicinity of the portable wireless device, such as being in the same room.

  • Patent number: 8181747
    Abstract: A bicycle sprocket chain cleaning and lubrication apparatus allows a sprocket chain (3) to be cleaned while still mounted on the bicycle. The apparatus includes a includes a housing (10) for enclosing the sprocket chain on all sides consisting of mutually connectable upper half-shell (11) and lower half-shell (12) portions and a securement assembly which includes a mounting plate adapted to attach to a rear wheel quick disconnect of the bicycle. The housing is suspended from the sprocket chain and provides a funnel shaped solvent hopper (17), a hose connection (21) to a compressed air supply, and an air knife (23) adapted to direct high velocity air to impinge upon and thereby dry the sprocket chain.

  • Patent number: 8150074
    Abstract: An impedance matched connection is provided between a load and a power source that outputs signals within a predetermined frequency range. A coaxial line has a predetermined characteristic impedance and an inner conductor, an outer conductor, and an insulator the two conductors. Each conductor has a first end electrically connectable to output terminals of the power source. A compensation circuit has an adjustable impedance, a first terminal electrically connected to a second end of the inner conductor and to a first terminal of the load, and a second terminal electrically connected to a second end of the outer conductor and to a second terminal of the load. The compensation circuit is sufficiently adjustable to attain, for a pulse having a rise time/fall time faster than those associated with the predetermined range of frequencies, a combined impedance and load that is substantially equal to the characteristic impedance of the coaxial line.

  • Patent number: 8102375
    Abstract: A dimmable keypad device (20) includes a plurality of dimming curves stored in memory where each dimming curve corresponds to a combination of background and foreground colors. The dimmable keypad device includes a backlight (203), an ambient light sensor (201) to adjust the illumination of the backlight, key capsules (102) fabricated from substantially transparent plastic and having an opaque paint layer coating their outer surfaces. Key capsule lettering (103) is formed by the removal of a portion of the opaque paint layer and the lettering color, as seen by an observer (42), is formed by backlight illumination of the substantially transparent plastic. The backlight illumination is relatively high under a low ambient lighting condition and relatively low under a high ambient lighting condition when the opaque paint layer is white.
