| 20080197591 | Hand truck - A hand truck includes a frame, a telescopic handle pivotally connected with the frame, and a joint structure assembled between the frame and the handle. The frame is disposed with a collapsible wheel unit adjustable in position, and the handle and the frame can be bent and extended to a proper length and then fixed in position so that a user can push the hand truck with convenience. Further, the hand truck can be shaped alternately into a two-wheel vertical truck or a four-wheel platform hand truck. | 08-21-2008 |
| 20090019670 | Castor - This invention is a castor, including the castor main body, brake system, directional system, release mechanism and a number of positioning elements. One side of the castor main body has a brake system and a directional system, allowing the user to easily carry out braking or release the brakes simply by pressing the brake system or directional system, making the brake flexible platelet move and press against the wheel surface. Also because the fluted disc on the brake system and the brake flexible platelet is combined into one, the fluted disc will, at the same time, move up and engage with the direction change fluted disc, applying the brakes and maintaining direction. By pressing down the directional system the castor can also be set to move in a straight line only. | 01-22-2009 |
| 20110175307 | Handcart - The invention relates to a handcart composed of a main frame, four wheel sets properly assembled under the main frame, a grip, two positioning sleeves, and two joint assemblies installed between the main frame and the grip for changeably connecting the main frame with the grip. The grip can be aligned flat or become 90° to the main frame by means of the joint assemblies. Then the handcart can be transformed as a two-wheel handcart or a four-wheel one by handling the grip through movement of the pivotal connecting bases of the joint assemblies and combining the grip with the positioning sleeves movably fitted in positioning holes of the grip. | 07-21-2011 |

| 20090046605 | Uplink scheduling grant for time division duplex with asymmetric uplink and downlink configuration - Singalling uplink and downlink scheduling grants for a plurality of subframes in a time division duplex frame is addressed. In one aspect the allocated uplink subframes are divided into groups, so the number of groups equals the number of downlink subframes being allocated. Uplink grants for the groups are sent with the downlink grants, and for those groups that have more than one uplink subframe, the grant message also indicates which uplink subframes are included in that group. In another aspect there are two sets of grant messages, one for the uplink subframes and one for the downlink subframes. Each of the uplink grant messages is sent on a different uplink grant message, and there is a one-to-one correspondence between the uplink grant channel and the uplink subframe being scheduled by the grant. That correspondence may also be signalled with the grant messages. | 02-19-2009 |
| 20090207811 | FREQUENCY QUALITY CRITERIA FOR INTER-FREQUENCY HANDOVER IN A TD-CDMA COMMUNICATION SYSTEM - A method for determining whether to perform handover of a UE apparatus to a candidate cell and carrier frequency of a TD-CDMA telecommunications network (such as a TD-SCDMA network) based separately on coverage and capacity, using one decision metric for coverage (e.g. based on received signal code power for the candidate cell and carrier frequency) and a different decision metric for capacity (e.g. based on a quantity proportional to the received signal code power for the candidate cell and carrier frequency and inversely proportional to a measure of total interference in the candidate cell on the carrier frequency. Corresponding equipment and a computer program product are also provided. In deciding whether handover is needed based on capacity, a threshold for received signal code power may be used in addition to the metric for capacity. | 08-20-2009 |
| 20100074189 | Scheduling metric for delay sensitive traffic - Disclosed is a method, a computer-readable memory medium and apparatus to create a combined priority list that comprises both uplink users and downlink users ordered by priority for use in scheduling user transmissions based on their respective priority locations in the combined priority list. In an exemplary embodiment a first set of users are retransmission users, a second set of users are delay sensitive users, and a third set of users are other users that are neither retransmission users or delay sensitive users. The set of retransmission users has a higher priority than the set of delay sensitive users, which in turn has a higher priority than the set of other users. | 03-25-2010 |
| 20110075684 | Enhanced Control Signaling For Backhaul Link - A method includes composing downlink control information having a format configured to support a presence of a plurality of transport blocks in a single subframe, where the downlink control information comprises, for the plurality of transport blocks, a common resource allocation and modulation/coding scheme field and a single cyclic redundancy check field. The method further includes transmitting the composed downlink control information to a relay node over a wireless link that comprises a backhaul link from the relay node. | 03-31-2011 |
