    摘要： Traditionally, learning speech synthesis and speech recognition were investigated as two separate tasks. This separation hinders incremental development for concurrent synthesis and recognition, where partially-learned synthesis and partially-learned recognition must help each other throughout lifelong learning. This invention is a paradigm shift—we treat synthesis and recognition as two intertwined aspects of a lifelong learning robot. Furthermore, in contrast to existing recognition or synthesis systems, babies do not need their mothers to directly supervise their vocal tracts at every moment during the learning. We argue that self-generated non-symbolic states/actions at fine-grained time level help such a learner as necessary temporal contexts. Here, we approach a new and challenging problem—how to enable an autonomous learning system to develop an artificial motor for generating temporally-dense (e.g., frame-wise) actions on the fly without human handcrafting a set of symbolic states. Here the artificial motor corresponds to a combination of a multiplicity of robotic effectors, including, but not limited to, speaking, singing, dancing, riding a bike, swimming, and driving a car. The self-generated states/actions are Muscles-like, High-dimensional, Temporally-dense and Globally-smooth (MHTG), so that these states/actions are directly attended for concurrent synthesis and recognition for each time frame. Human teachers are relieved from supervising learner's motor ends. The Candid Covariance-free Incremental (CCI) Principal Component Analysis (PCA) is applied to develop such an artificial speaking motor where PCA features drive the motor. Since each life must develop normally, each Developmental Network-2 (DN-2) reaches the same network (maximum likelihood, ML) regardless of randomly initialized weights, where ML is not just for a function approximator but rather an emergent Turing Machine. The machine-synthesized sounds are evaluated by both the neural network and humans with recognition experiments. Our experimental results showed learning-to-synthesize and learning-to-recognize-through-synthesis for phonemes. This invention corresponds to a key step toward our goal to close a great gap toward fully autonomous machine learning directly from the physical world.

    摘要： An alarm system at a premises reduces the overall delay in signalling an alarm condition in the presence of an entry delay timer. The alarm system establishes, or commences the establishment of a network connection prior to the expiry of the entry delay. This allows an alarm message to be quickly dispatched upon expiry of the entry delay timer, or if a tamper condition is sensed.

    摘要： A carbon fiber arrow shaft comprises a hollow tube, a reinforced carbon fiber, and a resinoid binder. The hollow tube has a length between 500-900 mm, an inner diameter between 2-10 mm, and a tube wall thickness between 0.3-2 mm. The reinforced carbon fiber and the resinoid binder form a resin-impregnated carbon fiber. The carbon fiber arrow shaft is formed by directly and continuously winding the resin-impregnated carbon fiber around the hollow tube. The carbon fiber arrow shaft has a head section (L1), a middle section (L2) and a tail section (L3). A winding angle of the carbon fiber at the head section (L1) is changed from a larger winding angle to a smaller winding angle, a winding angle at the middle section (L2) stays constant, and a winding angle at the tail section (L3) is changed from a smaller winding angle to a larger winding angle. The lengths of the head section (L1) and the tail section (L3) are between 25-250 mm. The initial winding angle at the head section (L1) is between 30-90 degrees and is gradually decreased to between 2-30 degrees at the boundary of the head section (L1) and the middle section (L2). The winding angle at the middle section (L2) stays constant, and the winding angle at the tail section (L3) is gradually increased from between 2-30 degrees at the boundary of the middle section (L2) and the tail section to between 30-90 degrees at the end of the tail section (L3). The peripherally located winding angles at both the head section (L1) and the tail section (L3) are at least two times the winding angle at the middle section (L2). The shaft provides uniformity of wall thickness and eliminates overlapping joints or surface protrusions.
