Abstract: Systems, devices and methods provide an RF coil which produces a field having linear phase variation across an imaging volume. In one embodiment, a coil comprises multiple microstrip elements configured to have an increased effective electrical length. This increase in electrical length allows for a larger linear phase shifts over the length of the microstrip element which in turn increases linear phase variation capabilities. This may be accomplished by increasing the effective dielectric properties of the microstrip element. Increasing the effective dielectric may be accomplished by utilizing distributed capacitors along the length of a microstrip element (e.g. lumped element capacitors), by altering the materials used to fabricate the microstrip element, etc. Additionally, increasing the effective dielectric may be accomplished using a combination of these means.

Abstract: A single electron tunneling force spectroscopy (SETFS) system (10) can perform a series of surface potential charge measurements at an array of voltages (V) and tip-sample heights (Z). These measurements are combined with a tunneling model that includes the dependence of the tunneling probability on trap state depth and energy. Simultaneous measurement of the depth and energy of individual trap states in a sample, such as a dielectric film, with an atomic scale of spatial resolution can be achieved. When combined with two-dimensional trap state imaging, such techniques provide for three-dimensional imaging of electronic defect states with atomic scale spatial resolution.

Abstract: Identifying valid wireless access points based on clock skews. A computing device receives plurality of frames, each including a corresponding timestamp, from a wireless access point. The computing device calculates transmit and receive offsets based on transmit and receive times of the plurality of frames, and also calculates differences between the transmit and receive offsets. The computing device also calculates a clock skew of a clock at the wireless access point based on a slope of the differences. The client computing device determines whether the wireless access point is an authorized wireless access point or an unauthorized wireless access point based on comparing the calculated clock skew with one or more known baseline clock skews of one or more authorized wireless access points.

Abstract: Methods, compositions, and systems for detecting gamma radiation is disclosed and described. A compound for detecting gamma radiation can comprise a conjugated imidazole having the following structure: [Formula I] where at least one of R1, R2, and R3 are conjugated organic groups.

Abstract: Disclosed is a spotter device and methods for the formation of microassays, biochips, biosensors, and cell cultures. The spotter may be used to deposit highly concentrated spots of protein or other materials on a microarray slide, wafer, or other surface. It may also be used to perform various chemistry steps on the same spots. The spotter increases the surface density of substances at each spot by directing a flow the desired substance (or a solution thereof) over the spot area until surface saturation is accomplished. The spotter may be loaded by well plate handling equipment. The spotter uses wells, microfluidic conduits, and orifices to deposit proteins, other biomolecules, or chemicals on a spot on, a separate surface. Each orifice is connected to two wells via microconduits. When the spotter contacts a surface, a seal is formed between the orifices and the surface. The same or different substances may be flowed across each orifice. Any number of orifices may be incorporated into a spotter.

Abstract: The ability of a receiver to determine when a transmitter has changed location is important for energy conservation in wireless sensor networks, for physical security of radio tagged objects, and for wireless network security in detection of replication attacks. In embodiments of the present invention, a measured temporal link signature is determined to uniquely identify the link between a transmitter and a receiver. The temporal link signature is an impulse response of a transmitted signal from the transmitter over a channel between the transmitter and a receiver over a channel. When the transmitter changes location, or if an attacker at a different location assumes the identity of the transmitter, the proposed link distinction methodology reliably detects the change in the physical channel. This detection can be performed at a single receiver or collaboratively by multiple receivers.
