摘要:
The invention relates to n optoelectronic sensor having a transmitter (12) for the transmission of a transmitted light beam (22) which is extended perpendicular to the detection direction by means of an optical transmission system (24) and a receiver (14) for the reception of received light (28) and for the provision of an electronic received signal, and an evaluation unit (16) for the recording of the received signal and for the outputting of an object detection signal, wherein at least the transmitter (12) and the optical transmission system (24) are arranged in a sensor housing (18) having a front screen (20). To provide an improved sensor which is inexpensive and nevertheless generates a linear transmitted light of high quality, it is proposed that the front screen (20) is overlaid with patterns (40) of light absorbing material for light intensity homogenization in a region (21S) through which the transmitted light (22) passes and/or in a region (21E) through which the received light (28) passes.

A method for converting a signed fixed point number into a floating point number that includes reading an input number corresponding to a signed fixed point number to be converted, determining whether the input number is less than zero, setting a sign bit based upon whether the input number is less than zero or greater than or equal to zero, computing a first intermediate result by exclusive-ORing the input number with the sign bit, computing leading zeros of the first intermediate result, padding the first intermediate result based upon the sign bit, computing a second intermediate result by shifting the padded first intermediate result to the left by the leading zeros, computing an exponent portion and a fraction portion, conditionally incrementing the fraction portion based on the sign bit, correcting the exponent portion and the fraction portion if the incremented fraction portion overflows, and returning the floating point number.

A radiation therapy system and method, especially for brachytherapy, monitors and verifies dose delivered at a plurality of points at or near the region to be irradiated, integrating verification with radiation delivery. In one procedure, mapping is used to determine the shape and location of the region to be irradiated. A treatment plan is developed using the mapping information and a dose prescription. As radiation is delivered to the target region internally, preferably using an electronic radiation source, the dose received at plural points is monitored and continually fed to a central processor. As needed based on feedback, the system modifies the treatment plan and delivery of radiation accordingly, to arrive substantially at the prescribed dose at all locations in the region. In a modified procedure the treatment is done according to a prescription dose but without a treatment plan by multiple iterations of source pullback and feedback and analysis of dose received in the tissue. Source radiation levels and/or pattern and dwell are modified for each successive iteration and preferably for different dwell points in an iteration.

A method for printing an interrupt print job including the steps of receiving a primary print job and processing the primary print job with a primary processor to provide a plurality of primary pages to a print queue. The method further includes the steps receiving an interrupt print job and processing the interrupt print job with an interrupt processor to provide at least one interrupt page. The method further includes the step of printing the at least one interrupt page prior to printing at least one primary page in the page queue.

An Enhanced Shared Secret Provisioning Protocol (ESSPP) provides a novel method and system for adding devices to a network in a secure manner. A registration process is launched at two network devices together within a predetermined time interval. These two devices then automatically register with each other. When two devices running ESSPP detect each other, they exchange identities and establish a key that can later be used by the devices to mutually authenticate each other and generate session encryption keys. With ESSPP, two ESSPP devices that are attempting to register with each other will only provision a key when they detect that they are the only two ESSPP devices on the wireless network running ESSPP. If additional devices running ESSPP are detected, the ESSPP protocol is either terminated or suspended.

A heating system in a motor vehicle having an engine mounted in front and has a heater enclosure which is arranged on the fire wall on the side facing the occupant compartment and houses a heat exchanger that is connected to the cooling water circuit of the engine. The heater enclosure is open at the end facing the fire wall and is fastened to the fire wall so that its open end surrounds a corresponding opening provided in the fire wall. The heat exchanger extends from the engine compartment through the opening in the fire wall into the inside of the heater enclosure. The installation of the heat exchanger into the heater enclosure proceeds in conjunction with the assembly of the modular-type vehicle.
摘要:
A processor obtains input of a logistically attainable end tidal partial pressure of gas X (PetX[i]T) for one or more respective breaths [i] and input of a prospective computation of an amount of gas X required to be inspired by the subject in an inspired gas to target the PetX[i]T for a respective breath [i] using inputs required to utilize a mass balance relationship, wherein one or more values required to control the amount of gas X in a volume of gas delivered to the subject is output from an expression of the mass balance relationship. The mass balance relationship is expressed in a form which takes into account (prospectively), for a respective breath [i], the amount of gas X in the capillaries surrounding the alveoli and the amount of gas X in the alveoli, optionally based on a model of the lung which accounts for those sub-volumes of gas in the lung which substantially affect the alveolar gas X concentration affecting mass transfer.
