    摘要: A radiotelephone proximity detector including a first proximity unit having a receiver and a second proximity unit having a transmitter, wherein the units can be coupled together and the coupling can be detected. One of the units is associated with a radiotelephone and the other with a user. When the units are coupled, they are responsive to the detection of their uncoupling, whereupon the transmitter of the second proximity unit transmits a proximity signal to the receiver of the first unit. The first proximity unit estimates the proximity of the radiotelephone and the user on the basis of the received proximity signal. Thus the two units operate together such that, when coupled, at least one of the units enters a standby mode, and when uncoupled, at least one of the units sends a proximity signal to the other unit.

    摘要: Methods and devices are provided for guiding and inserting a tool into an object, such as tissue. In an exemplary embodiment, a guidance and insertion device is provided that can be remotely controlled to adjust an insertion trajectory of a tool, and to advance the tool into tissue to a desired penetration depth. The tool can be, for example, a biopsy device, a brachytherapy device, or a lumpectomy device. The device can be configured for use with an imaging apparatus, such as computed tomography (CT) images, to allow the device and tool to be operated while viewing the device positioned in relation to a target surgical site. The device can also be configured to be positioned directly on a patient, so as to passively compensate for respiratory chest motion, and it can include features to passively compensate for needle oscillation. In other exemplary embodiments, the device can be entirely disposable.
