May 11, 2010

Appl. No.:

12/777819

Inventors:

Jeffrey Pang - Menlo Park CA, US
Stephen Y. F. Pang - Menlo Park CA, US

David Pang - Menlo Park CA, US

International Classification:

H04R 25/00

US Classification:

381374, 381370

Abstract:

A headphone having reduced tendency to tangle comprises an input portion for receiving electrical signals from an output device, an output portion for providing audio signals to a user in response to the electrical signals, a plurality of wires coupled to the input portion and the output portion for providing the electrical signals to the output portion, and a restraint mechanism coupled to the plurality of wires and cable of being repositioned along the plurality of wire, wherein the restraint mechanism is for physically receiving insertion of at least a portion of the input portion and for physically restraining movement of the portion of input portion with respect to output portion when the portion of the input portion is physically inserted into the restraint mechanism, wherein a temporary and removable closed loop of wire is formed from the plurality of wires, until a sufficient separation force is applied.

David Pang - Menlo Park CA, US
Stephen Y. F. Pang - Menlo Park CA, US

International Classification:

H04R 1/10

US Classification:

381384, 381385

Abstract:

A headphone having reduced-tangling potential includes an audio plug for receive electrical signals from an audio device, coupled via wires to ear buds, wherein the ear buds are for receiving electrical signals and outputting audio, wires coupled to the audio plug and to the pair of ear buds, wherein the coupling wire is configured to provide the electrical signals from the audio plug to at least the pair of ear buds, and a restraint device having a pliable material body having an interior channel, wherein the channel restrains movement of the separate ear buds a first resistance, when the audio plug is inserted into the channel, and wherein the channel restrains movement the separate ear buds by a second resistance, when the audio portion is separated from the channel, wherein the first resistance amount exceeds the second resistance amount.

Stephen Y.F. Pang - Menlo Park CA, US

International Classification:

H04R 1/10

US Classification:

381384

Abstract:

A restraint device for a pair of headphones having a pair of earphones, an audio plug, and a pair of wires coupling the pair of earphones to the audio plug, wherein the restraint device includes a body of a material, wherein the material includes an interior channel, wherein the interior channel is configured to have the pair of wires be slidably disposed therein, wherein the interior channel is configured to have the audio plug be removably disposed therein, wherein the interior channel is configured to restrain relative movement of the pair of wires with respect to the audio plug when the pair of wires and the audio plug are disposed adjacently within the interior channel.

Jul 13, 1992

Appl. No.:

7/912311

Inventors:

Donald Pang - Fremont CA
David K. Pang - Pleasanton CA

International Classification:

G01L 1500

US Classification:

7337902

Abstract:

A precision grip meter includes a frame; a base on the frame sized and shaped to engage the palm of the hand; a plurality of plungers on the frame opposite the base and located for being depressed by corresponding fingers of the hand; and a device associated with the base and the plungers for simultaneously measuring and recording both finger strength and overall hand strength. The grip meter may also comprise a frame; a force-detecting device; a first system on the frame for receiving the fingers of a hand and applying force exerted by the fingers to the force-detecting device; and a second system on the frame for receiving the heel of the hand and applying force exerted by the heel to the force-detecting device. Preferably, the grip meter is symmetrical so that it can be used for measuring the finger and hand strength of either the left hand or the right hand.

Appl. No.:

14/940054

Inventors:

David H. Pang - Rowland Heights CA, US

International Classification:

A63F 1/00
G07F 17/32

Abstract:

A method for increasing a wager during a blackjack card game allows a player to at least double the wager after receiving at least one Ace card in an initial card distribution; wherein the increased wager is supplied from a dealer if the at least one Ace card substantially matches another card from the initial card distribution; wherein the increased wager is supplied by the player if the at least one Ace card does not match another card from the initial card distribution. The comparative card game includes black jack. The player can double down on the initial wager if one of the two cards in the initial deal is an Ace card. If the color or suit of the Ace card matches the second card in the initial deal, the player can use house money to double down; otherwise the player must use other funds.
