Assignee:

SOP Services, Inc. - Las Vegas NV

International Classification:

A63B 67/04

US Classification:

473496

Abstract:

A multi-section table tennis table half comprises first and second table sections which abut to form a first table half. Each of the sections includes an upper surface for playing table tennis, an opposite lower surface an inner edge. The inner edges of the first and second sections abut to form a first table half joint. The vertical cross-section of the joint may be stepped, with each of the inner edges being stepped and thereby including a horizontal section positioned between two vertical sections. The table half may further include a fastener spanning the abutment between the sections to secure the connection of the sections.

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04J 3/06

US Classification:

370350

Abstract:

A transmitting device transmits data to one or more receiving devices. At least one of the receiving devices transmits a keep-alive to the transmitting device. The keep-alive is transmitted at a reduced rate relative to the data transmission rate. In some implementations multiple receiving devices may transmit keep-alives. In these cases, each receiving device may transmit its keep-alives according to a schedule to prevent or reduce the likelihood of overlapping keep-alives. In some implementations a receiving device may be selected to transmit keep-alives. Here, if the selected receiving device stops transmitting keep-alives another receiving device is selected to transmit keep-alives. Through the use of the above techniques, the transmitting device need not keep track of which receiving devices are listening to the data transmission. Rather, the transmitting device may simply stop transmitting in the event that it no longer receives keep-alives.

Appl. No.:

12/355008

Inventors:

Zhanfeng Jia - Belmont CA, US
David Jonathan Julian - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04W 72/04

US Classification:

370329, 370349, 455450

Abstract:

In an addressing scheme for wireless communication a communication channel may be defined based on a unique identifier associated with a destination node or a source node. In addition, a short identifier may be included in messages sent over the communication channel such that a node may uniquely identify the source node or destination node for the message. A node may use a short identifier as an index into a lookup table to determine one or more parameters to be used for communicating with another node.

International Classification:

H04K 1/10
H04B 7/02

US Classification:

375260, 375267

Abstract:

A system and method for media access control are disclosed. The method comprises providing concurrent orthogonal channels to access media using pulse division multiple access to define pulse positions, wherein the pulse division multiple access includes a time hopping sequence and an offset to distinguish the concurrent orthogonal channels. In addition, the method comprises processing signals associated with at least one of the orthogonal channels.

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04L 12/56

US Classification:

370394, 370231

Abstract:

A communications method comprising the steps of receiving a data packet; processing the data packet; and transmitting an ack packet approximately at an end of a first defined time interval if the processing of the data packet is completed within the first defined interval, or transmitting the ack packet approximately at an end of a second defined time interval if the processing of the data packet is not completed within the first defined interval and is completed within the second defined interval. Another communication method comprising the steps of transmitting a data packet; scanning a channel for an ack packet approximately at an end of a first defined time interval from the transmission of the data packet; and scanning the channel for the ack packet approximately at an end of a second defined time interval from the transmission of the data packet if the ack packet was not received within the first defined interval.

International Classification:

H04H 20/71
H04J 9/00
H04J 3/16

US Classification:

370312, 370465

Abstract:

A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.

US Classification:

473496

Abstract:

Certain embodiments comprise a table tennis table having a table tennis surface defined by two table halves and separated by a net. Each table half has an upper playing surface, a width defined between opposing side edges and a player end arranged along the width. In one embodiment, the table tennis table includes a ball storage rack having a length mounted along the width of at least one table half adjacent the player end, wherein the ball storage rack is configured to support a plurality of table tennis balls. The ball storage rack defines a gap along its length, wherein the gap faces outward from the player end and has a size sufficient to allow table tennis balls to be selectively removed through the gap.
