An electrosurgical system has an electrosurgical generator and a bipolar electrosurgical instrument, the generator being arranged to perform a treatment cycle in which radio frequency energy is delivered to the instrument as an amplitude-modulated radio frequency power signal in the form of a succession of pulses characterized by periods of a least 100 milliseconds between successive pulses and by a predetermined pulse mark-to-space ratio. Energy delivery between pulses is substantially zero and the mark-to-space ratio is typically 1:4 or less. Each burst is of sufficiently high power to form vapor bubbles within tissue being treated and the time between successive pulses is sufficiently long to permit condensation of the vapor. The treatment cycles may each include an initial period and a subsequent period, the pulse duty cycle being increased or energy being delivered continuously in the subsequent period in order that tissue coagulation can be achieved quickly despite increasing tissue impedance.

Also described is a technique for initialization and vehicle control using only a single pseudolite.

A two-dimensional position sensor comprising a substrate with a sensitive area defined by a pattern of electrodes including electrodes for determining x-position and electrodes for determining y-position. The x-electrodes and y-electrodes generally extend in the x-direction and are interleaved in the y-direction. The x-electrodes comprise at least first, second and third groups of elements shaped such that adjacent ones of the elements of the different x-electrode groups co-extend in the x-direction so that the x-electrodes provide ratiometric capacitive signals, thereby providing quasi-continuous x-position sensing across the sensitive area. In addition, the y-electrodes may be resistively connected or arranged in ratiometric pairs to provide quasi-continuous y-position sensing. Alternatively, the x-electrode groups may be interdigitated to form pairs of x-adjacent blocks of differing area to provide stepwise x-position sensing in combination with stepwise y-position sensing provided by the y-electrodes.

Embodiments of the invention are directed to methods, a computer-readable medium, servers and systems for enabling merchants to pass payment tokens, instead of actual payment information, to third party HOPs and SOPs. This, for example, enables a merchant to charge a consumer, such as on a recurring basis or for a one-off purchase, without having the consumer enter payment information each time and without the merchant actually having to handle payment information. As such, merchants can avoid costs and responsibilities associated with handling and storing consumer payment data, while at the same time it also gives merchants the benefit of engaging in purchase transactions with consumers without requiring that the consumers reenter payment data each time they want to make a purchase.

An aerial reconnaissance system generates imagery of a scene that meets resolution or field of view objectives automatically and autonomously. In one embodiment, a passive method of automatically calculating range to the target from a sequence of airborne reconnaissance camera images is used. Range information is use for controlling the adjustment of a zoom lens to yield frame-to-frame target imagery that has a desired, e.g., constant, ground resolution or field of view at the center of the image despite rapid and significant aircraft altitude and attitude changes. Image to image digital correlation is used to determine the displacement of the target at the focal plane. Camera frame rate and aircraft INS / GPS information is used to accurately determine the frame to frame distance (baseline). The calculated range to target is then used to drive a zoom lens servo mechanism to the proper focal length to yield the desired resolution or field of view for the next image. The method may be performed based on parameters other than range, such as aircraft height and stand off distance.
