Emission of a signal in unused resource units to increase energy detection of an 802.11 channel
In an 802.11ax network with an access point, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access point. To avoid the overall energy level seen by legacy nodes for a communication channel to drop below a detection threshold, the invention provides two tools. First, the scheduled and random resource units may be interleaved over communication channels. Second, unused resource units may be detected, and a node or the access point may send a padding signal on them to increase the overall energy level. The latter may be evaluated during a monitoring period before deciding to emit the signal. As the overall energy level seen by legacy nodes is increased, the risk that such legacy nodes do not detect activity on a 20 MHz channel having only a subpart of its RUs used is reduced. And risks of collisions are consequently reduced. |

An omnidirectional sound source is formed by mounting a loudspeaker in an enclosed baffle, preferably formed as a low profile hemi-spherical, convex cap with a small circular orifice at its apex and a planar base. The loudspeaker is mounted within the baffle, affixed to the underside of the baffle cap directly beneath the orifice. Substantially plane audio-frequency wavefronts emanating from the immediate vicinity of the loudspeaker diaphragm pass through the orifice and, by the process of diffraction emerge as spherical waves. The spherical wavefronts follow the smooth, axisymmetric, gently curved contour of the low-profile, hemispherical baffle and are not distorted by edge effects where the baffle joins its planar base. As a result, an omnidirectional sound source is obtained. |

Further, for an uncertainty period that extends from the minimum expected transition duration after the starting to the maximum expected transition duration after the starting, the device generates and plays a sequence of transition frames to help mask transition from the first media stream to the second media stream. |

Coding of quantization matrices using parametric models
Quantization matrix can be used to adjust quantization of transform coefficients at different frequencies. In one embodiment, a single fixed parametric model, such as a polynomial is used to represent a quantization matrix. Modulation of bit cost and complexity is achieved by specifying only the n first polynomial coefficients, the remaining ones being implicitly set to zero or other default values. One form of the single fixed polynomial is a fully developed polynomial in (x,y), where x,y indicate the coordinates of a given coefficient in a quantization matrix, with terms ordered by increasing exponent. Since higher exponents are the last ones, reducing the number of polynomial coefficients reduces the degree of the polynomial, hence its complexity. The polynomial coefficients can be symmetrical in x and y, and thus reducing the number of polynomial coefficients that need to be signaled in the bitstream. |

Wire stripper
A wire stripper for stripping cables has two plier jaws, two outer clamping jaws, two inner cutting jaws, and two gripping parts. The cutting jaws can be displaced from a starting position into an end position by a pull rod while pressing together the gripping parts. The cutting jaws are guided on sliding block parts that rest against a sliding block fixed in the clamping jaws. The cutting jaws are moved toward each other to varying degrees through these sliding block parts, depending on a closed position of the clamping jaws, with the closed position determining the movement of the sliding block part. The sliding block parts can be manually adjusted independently of a closed position of the clamping jaws in terms of a position relative to the sliding block, while at the same time acting on both sliding block parts. |
