An optic element receives an input light beam with a first beam angle and an axis. The optic element includes a first surface that receives the input light beam and generates an expanded light beam with a second beam angle that is greater than or equal to the first beam angle. The optic element includes a second surface that receives the expanded light beam and generates an output light beam that is either substantially collimated or near collimated. The output light beam is tilted a predetermined degrees with respect to the axis of the input light beam.

A tree trimming device that automatically climbs a tree or other vertical member and shears limbs or debris as it climbs has an anchor structure, a cutting assembly, vertical connecting pistons, and a cutting blade assembly. The anchor structure and the cutting assembly may be attached by vertical connecting pistons. The device climbs vertical members by clamping the anchor structure to the tree or other vertical member, then extending the vertical connecting pistons, which forces the cutting assembly to move up the vertical member, shearing limbs or other debris as it moves. Once the vertical connecting pistons are extended, the cutting assembly may be clamped to the tree, and the vertical connecting pistons may be retracted, thus pulling the anchor structure up the vertical member towards the cutting assembly. The process may be repeated until the vertical member is trimmed to the desired height. The process may be reversed to lower the device back to the ground.

A bar code reading device having an image sensor including a plurality of pixels can be operated to capture a parameter determination frame of image data, wherein the parameter determination frame of image data includes image data corresponding to light incident at less than all of the pixels of the image sensor. A bar code reading device can also be operated in an image capture operating mode in which a partial frame of image data is captured, wherein the partial frame of image data includes image data corresponding to light incident at less all of the pixels of the image sensor, and wherein image data of the partial frame can be processed in order to attempt to decode a bar code symbol.

An identification circuit for establishing and sensing the state of a fusible element used in on chip identification of the chip's type comprising: a circuit establishing control signals for turning the identification circuit on and off; dual paths energized by the control signals generated by the level setting circuit to energize one path through the fusible element to provide a state level and the other path through a reference path which provides a reference voltage level which is distinguishable from both the blown and unblown states of the fusible element; a differential sensing circuit for comparing the reference voltage level to the state level to provide a signal indicating the state of the fusible element; and protection circuitry to protect the circuit during an operation in which the state of the fusible element is set.

An optical instrument for indirectly observing an object includes a first lens system for producing a first image of the object, and an adjustable second lens system for producing a second image of the object. The second lens system is continuously adjustable between a first position wherein the second image has maximum magnification and/or a minimum area of view, and a second position wherein the second image is of a minimum magnification and/or a maximum area of view. In one aspect of the invention, the second lens system is a zoom lens system having two substantially fixed conjugate planes. In another aspect of the invention, the instrument defines a folded optical path through the lens systems which includes a generally U-shaped portion so as, in use, to reduce the separation of the observer and the observed object.

A system and a method include a facility for storing and verifying transactions. A banking facility maintains deposit accounts. A healthcare provider supplies healthcare and or products. A purchasing platform enables a purchase of healthcare products. The purchasing platform is configured for communication with the facility and the banking facility. The purchasing platform is further configured for transmitting a value of a monetary instrument to the facility and the banking facility. The purchasing platform is further configured for receiving a voucher for the healthcare product. A patient presents the voucher to the healthcare provider and communicates information regarding the voucher and the healthcare provider to the facility and the banking facility. The information is verified. The healthcare provider is messaged with a confirmation of payment. The banking facility transfers a value of the voucher to the healthcare provider, and the healthcare provider supplies the patient with healthcare and or products.
摘要:
A method and apparatus for generating electric energy from the motion of the waves. The apparatus comprises at least one member which is moved by the motion of the waves. The apparatus also comprises an energy transfer mechanism coupled to the or each member. The energy transfer mechanism converts the kinetic energy from movement of the or each member to potential energy by pressurization of a fluid. The apparatus further comprises a first chamber, arranged to store the pressurized fluid and a conversion means for converting the potential energy stored in the pressurized fluid into electric energy. The apparatus can be arranged such that any substantially vertical displacement of the or each member causes actuation of the or each corresponding energy transfer mechanism.

A sorting system may include a sorting apparatus coupled to a programmable control system which is configured to actuate the sorting apparatus so that it assembles similar products for packaging in an arbitrary, user imposed order or selection bias. In preferred implementations, a user may activate a biasing protocol pursuant to which items bearing certain images appear with a disproportionate frequency on the top of a stack of items such that the selected images are the most common images viewable through a transparent product packaging. In certain implementations, empirical sales data is used to determine weighting factors used in the biasing protocol. In still other implementations, a more specific ordering protocol is imposed by a user such that some or all of the sequence of items in a stack or collection is arbitrarily imposed.
