An improved line of golf clubs tailored to the golfer. The face wall firstly is designed so that the face wall modulus of elasticity increases from a low modulus for the low swing speed range to progressively higher modula for the higher swing speed ranges. Face modulus can be altered by a variety of techniques including face wall thinning, material selection and heat treatment or a combination thereof. In each of the swing speed range clubs, the face has a first modulus of elasticity determined by the face itself and after the face deflects to a predetermined value, the face modulus is significantly increased by a secondary wall parallel to and closely spaced behind the face wall.

A Chinese text entry system with eye-tracking technique can be used for computer input of Chinese characters. The system is comprised of two main components: the Chinese pinyin software and the eye-tracking system. Chinese characters corresponding to pinyin input are selected from a list of candidate characters by selecting the proper character through eye-tracking identification and confirming the selection by pressing a readily accessible confirmation key. The Chinese pinyin software implements pinyin input at both the character and word level, choosing from multiple character or word homonyms as pinyin is entered. The system uses eye-tracking technology that is only used to identify the correct Chinese character, with the character selection and entry occurring when the confirmation key is pressed.

A wireless network node and a network provide for automatic self-deployment of the radio frequency channels without the need for preplanning. Each wireless network node adapts to the inclusion of a new node and to changing local conditions without requiring manual configuration at deployment or re-deployment. When a node is added to the network, it scans and finds its neighbors, and enters a frequency self-selection phase of its initialization process. The method for frequency self-selection involves transmitting and receiving a sequence of messages to / from neighbors and performing related processing within the controller unit of the node. Three sets of parameters are used in the frequency self-selection algorithm. The three parameter sets include a routing cost function, the frequencies in use by neighbors (and those that may be blocked), and the antenna beams used for the respective frequencies.

A method and system for eye-safe near infra-red (NIR) optical imaging illumination. An eye of an intended subject are imaged with visible light or NIR light at an unconditionally eye-safe illumination level and the maximum permissible eye-safe NIR illumination that can be applied to the eye is determined from the captured images. The eye of the intended subject can then be illuminated with at least one substantially maximal NIR light pulse having a pulse intensity and duration selected to provide the substantially maximum permissible eye-safe NIR illumination intensity at the eye. NIR light pulse illumination can be inhibited in response to detection of other subjects either within the vicinity of a volume extending between an NIR illuminator illuminating the eye and the intended subject. The likelihood that an intended subject has been recently illuminated can also be determined and statistical measures can be used to avoid re-illuminating subject unnecessarily.

A method distinguishes components of an acoustic signal by processing the signal to estimate a set of analysis features, wherein each analysis feature defines an element of the signal and has feature values that represent parts of the signal, processing the signal to estimate input features of the signal, and processing the input features using a deep neural network to assign an associative descriptor to each element of the signal, wherein a degree of similarity between the associative descriptors of different elements is related to a degree to which the parts of the signal represented by the elements belong to a single component of the signal. The the similarities between associative descriptors are processed to estimate correspondences between the elements of the signal and the components in the signal. Then, the signal is processed using the correspondences to distinguish component parts of the signal.

A method generates constant modulus multi-dimensional modulations for coherent optical communications by first projecting points in a constellation of the code onto a Poincare sphere or its higher-dimensional hyper-sphere. By using meta-heuristic procedures, nonlinear programming and gradient search methods, constellation points in the hyper-sphere are optimized in certain criteria, such as maximizing the minimum Euclidean distance, minimizing the union bound, minimizing the bit-error rate, minimizing the required signal-to-noise ratio, maximizing the nonlinear fiber reach, maximizing the phase noise tolerance, and maximizing the mutual information. Some methods use parametric unitary space-time block codes such as Grassmannian packing, and filter impulse response as well as unitary rotation over adjacent code blocks to generate near-constant modulus waveform, not only at the symbol timing, but also over the entire time.

The present invention is directed to a mathematical approach to detect faults by reconciling known data driven techniques with a physical understanding of the HVAC system and providing a direct linkage between model parameters and physical system quantities to arrive at classification rules that are easy to interpret, calibrate and implement. The fault modes of interest are low system refrigerant charge and air filter plugging. System data from standard sensors is analyzed under no-fault and full-fault conditions. The data is screened to uncover patterns though which the faults of interest manifest in sensor data and the patterns are analyzed and combined with available physical system information to develop an underlying principle that links failures to measured sensor responses. These principles are then translated into online algorithms for failure detection.
