摘要： Provided is an all-terrain trailer for hauling large objects over uneven landscapes. The trailer is capable of carrying items within its volume in both its deployed and stowed state. Deployed, the trailer is a basket shaped body with a pair of wheels removably secured via a removable axle. The trailer is attached to the lead vehicle using a removable trailer hitch linkage that is secured to the basket body via fasteners. In a stowed state, the tires and axle are stored within a storage area in a lower portion of the basket body. In one embodiment, a false bottom is placed over the storage area, creating a flat trailer bed that objects can be laid upon. The basket body is removably secured to the hood of a lead vehicle, thereby providing a carrying basket while the vehicle is in transit.

摘要： In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.

摘要： An apparatus and a method to track the channel response for subcarriers in an OFDM receiver for a packet of information that includes a known transmitted part. The receiver has a signal-to-tone transformer to determine subcarriers corresponding to a received packet. The method stores a function of an initial estimate of the channel response for a subcarrier, and accepts a pre-decision constellation point value that is a post channel correction using a first estimate of the channel response. The method includes: makes a decision using the pre-decision constellation point value, re-modulates the decision to form a post-decision constellation point value, and forms a complex valued product of the function of the first estimate for the subcarrier and the complex-valued ratio of the pre-decision and post-decision values. This complex valued product forms a measure of the current channel estimate to use for updating the stored quantity.
