Abstract: The shock-absorbing wheel barrow suspension system is a cart. The shock-absorbing wheel barrow suspension system is a manually powered rolling structure that is controlled by a single person. The shock-absorbing wheel barrow suspension system has a dual wheel structure. The combination of the dual wheel structure and the shock absorbing capability makes the shock-absorbing wheel barrow suspension system easier to control when compared to a traditional wheelbarrow.

Abstract: A transceiver includes a receive path including a low noise amplifier and a first switch coupled between the low noise amplifier and ground, a first transmit path including a low power amplifier and a second switch coupled between the low power amplifier and a main signal path, and a second transmit path including a high power amplifier and a third switch coupled between the main signal path and ground. The receive path is active when the first, second, and third switches are in an open position, the first transmit path is active when the first switch is in a closed position, the second switch is in the closed position, and the third switch is in the open position, and the second transmit path is active when the first switch and the third switch are in the closed position, and the second switch is in the open position.

Abstract: Apparatus and methods for performing wireless communications are provided. In some embodiments, an apparatus includes a transformer including a first winding, a second winding, and a third winding. The apparatus also includes a first transmitter circuit coupled with the first winding, and a second circuit coupled with the second winding. The third winding is coupled with an antenna. The first transmitter circuit is configured to transmit a first signal to the antenna via magnetic coupling between the first winding and the third winding. The second circuit is configured to tolerate without damage a second signal from the first transmitter circuit, wherein the second signal is generated from the first signal via magnetic coupling between the first winding and the second winding. A turn ratio between the first winding and the second winding can be configured to limit a voltage of the second signal to be within a pre-determined threshold.
