    Abstract: Electrolytic protection of steel-reinforced concrete bodies such as bridges and building facades is achieved with carbon material (3, 12, 23) inserted into the concrete body (6, 10, 21). The carbon material is connected to act as a anode with the steel reinforcement (1, 11, 22) as a cathode, so that corrosive chloride ions migrate away from the steel reinforcement. The carbon material is inserted so as also to act as a reinforcement. In one arrangement carbon textile material is provided between inner and outer grout-filled plastics ducts (2, 4, 5) fixed around post-tensioned steel cables (1). In another arrangement a carbon rod (12), or pin (23), is fixed between a concrete body (23) and a steel I-beam (22).

    Abstract: This invention relates to racquet stringing apparatus and includes a portable string tensioner and a portable string anchor. The tensioner operatively engages a frame of a racquet, grips a length of a string with which the frame is being strung, and, via displacement means thereof, tensions a length of the string. The string anchor operatively anchors to the frame a length of string that has been tensioned by the tensioner. Each of the string anchor and the string tensioner is thus a self-contained device that interacts between a racquet frame and a string only. The devices are used to sequentially tension string spans in a head part of a racquet frame during stringing of the frame. The devices are easily portable, for instance in a sports kit bag, which clearly may be convenient to a user.

    Abstract: A real-time radar surveillance system comprises at least one land-based non-coherent radar sensor apparatus adapted for detecting maneuvering targets and targets of small or low radar cross-section. The radar sensor apparatus includes a marine radar device, a digitizer connected to the marine radar device for receiving therefrom samples of radar video echo signals, and computer programmed to implement a software-configurable radar processor generating target data including detection data and track data, the computer being connectable to a computer network including a database. The processor is figured to transmit at least a portion of the target data over the network to the database, the database being accessible via the network by at least one user application that receives target data from the database, the user application providing a user interface for at least one user of the system.

    Abstract: A flat panel rectangular or elliptical loudspeaker has one or more anisotropic diaphragms (14, 15), made of double skinned fluted polypropylene copolymer (core flute) or corrugated cardboard, having a longitudinal bending strength greater than the transverse bending strength. The diaphragm is vibrated by a driver unit (16) which comprises a magnet (17) and voice coil (18). In this version the magnet (17) is mounted on the rear diaphragm (15) and the voice coil (18) is mounted on the front diaphragm (14). The two diaphragms (14, 15) are mounted at their edges to a frame (11) with the driver unit (16) mounted in the space enclosed by the frame and the diaphragms.

    Abstract: A 3D avian radar sampling system comprises a 3D volume scanning radar system and an avian track interpreter. The radar system tracks bird or other airborne targets within its local 3D surveillance volume which could be characterized by a cylinder with a typical range of 0 to 10 km and typical altitude of 0 to 10,000 ft above ground level. Special scanning methods are employed to ensure that volume revisit times are suitably short and track data produce 3D target trajectories, both of which are needed for avian activity reports to be meaningful and timely. The avian interpreter uses the track data from the volume scanning radar to create detailed avian activity reports that convey bird abundance and behavior within the 3D cylindrical volume on intervals including hourly, daily, weekly, monthly and yearly. Hourly activity reports (updated typically every 15 minutes) provide enhanced situational awareness of developing hazards and are actionable, allowing operators to dispatch wildlife control personnel to respond to threats. Older activity reports help uncover recurring patterns to guide management efforts. Applications include bird aircraft strike hazard (BASH) management and natural resource management. The apparatus and methods are equally suitable for other airborne targets such as general aviation aircraft and ultralights, making the invention appropriate for homeland security, as well as ground-based sense and avoid systems needed for unmanned aerial systems (UAS).

    Abstract translation: 3D鸟类雷达采样系统包括一个3D体积扫描雷达系统和一个鸟类轨道解释器。 雷达系统追踪其当地3D监视量内的鸟类或其他空中目标,其特征可能是典型的0至10公里范围内的气瓶以及地平线以上0至10,000英尺的典型海拔高度。 采用特殊扫描方法确保体积重访时间适当短,并且跟踪数据产生3D目标轨迹,这两种情况都是禽类活动报告有意义和及时所必需的。 禽类解释者使用来自体积扫描雷达的踪迹数据创建详细的禽类活动报告,以每小时,每天,每周,每月和每年的时间间隔在3D圆柱体积内传达禽类丰度和行为。 每小时的活动报告(通常每15分钟更新一次)提供增强的情境意识,开发危害并可采取行动,允许操作员派遣野生动物控制人员对威胁做出反应。 较早的活动报告有助于发现反复出现的模式以指导管理工作。 应用包括鸟类飞机起飞危险(BASH)管理和自然资源管理。 该装置和方法同样适用于其他空中目标,例如通用航空飞机和超轻型飞机,使得本发明适用于国土安全,以及地基感和避免无人航空系统(UAS)所需的系统。
