Scalable RFID systems: a privacy preserving protocol with constant-time identification
A protocol with constant-time complexity solves the problem of private identification of tags in low-cost, large-scale radio frequency identification (RFID) systems—assuming that an adversary has complete control over the communication channel. Each RFID tag has an internal counter, c, and is preloaded with a unique pseudonym, ψ, and a secret key, k. A RFID reader attempting to identify and authenticate a tag within its range generates and transmits a random nonce to the RFID tag, which returns a first hash of its current pseudonym and counter, and a second hash that is a function of the secret key. The reader uses the returned data to identify the RFID tag and its secret key by reference to a database and returns other hash values that authenticate the reader to the RFID tag. The most expensive operation that RFID tags are required to perform is a hash function.

Iterative algorithms for variance reduction on compressed sinogram random coincidences in PET
The use of the ordinary Poisson iterative reconstruction algorithm in PET requires the estimation of expected random coincidences. In a clinical environment, random coincidences are often acquired with a delayed coincidence technique, and expected randoms are estimated through variance reduction (VR) of measured delayed coincidences. In this paper we present iterative VR algorithms for random compressed sonograms, when previously known methods are not applicable. Iterative methods have the advantage of easy adaptation to any acquisition geometry and of allowing the estimation of singles rates at the crystal level when the number of crystals is relatively small. Two types of sonogram compression are considered: axial (span) rebinning and transaxial mashing. A monotonic sequential coordinate descent algorithm, which optimizes the Least Squares objective function, is investigated. A simultaneous update algorithm, which possesses the advantage of easy parallelization, is also derived for both cases of the Least Squares and Poisson Likelihood objective function.

Thermally independent overcurrent tripping device
Exemplary embodiments are directed to an electrical overcurrent tripping device for a circuit breaker. The tripping device includes an actuating member which in case of an overcurrent is driven to interact directly or indirectly with a movable contact piece of the circuit breaker to open a contact point in the circuit breaker if the overcurrent is exceeding a preset tripping threshold for a predetermined tripping delay time.

The actuating member is coupled to an electromagnetic damping arrangement to set the tripping delay time, and is connected to a coupling spring configured to adjust the overcurrent tripping threshold.
Impedance tuners with resonant probes
Slide screw impedance tuners use resonant probes in order to avoid uncontrollable reflection factors at harmonic frequencies in high power load pull transistor testing. The tuners use either coaxial slotted airlines or slablines. The probes are coupled capacitively with the central conductor of the airline and are either slotted with associated spring loaded effect for better galvanic ground contact, or solid dielectrically coated or anodized and carefully machined for slide fitting into the slabline opening or the coaxial line slot, for capacitive contact with the ground plane. The probes allow for selective reflection behavior over a given frequency range, which does not include unwanted frequencies, such as harmonic or sub-harmonic frequencies.
