摘要： In a gun sight the objective lens system 4 is designed to produce a larger than normal image and the eye-piece 6 is designed to be adjusted so as to view different parts of the image. This allows the gunner to view features which are significantly off-axis without interfering with the bore- sighting of the gun.

摘要： A mixer incorporating FET's (4,5) as the switching elements includes a resonant circuit connected as a tank circuit of the local oscillator (6) such that the inherence capacitance of the FET's is automatically compensated for. The harmonic recovery technique is also used by the inclusion of rejection filters at the input and output of the system, which rejection filters have reciprocal impedance characteristics, such as short circuit/open circuit or the like.

摘要： A cooling arrangement for high power components such as semi-conductors (1) includes a chamber (10), a lower portion (3) of which contains a liquid (11) to which heat can be applied to vaporise some of the liquid. An upper portion (5) of the chamber constitutes a condensation region at which vaporise liquid is condensed. Means (14,15) is included for monitoring a difference in temperature between the upper and lower portions and which is indicative of an incomplete filling of the chamber with the liquid and its vapor.

摘要： At each node of a ring there are receive (RX) and transmit (TX) shift registers in series with the ring for the transfer from and to the ring of packets of a common length, a receive clock data-locked to the received data for clocking the receive register (RX), and an independant transmit clock for clocking the transmit register (TX). The transmit clock is triggered on at the instant that a synchronisation bit in the packet is received in the receive register (RX), i.e. after a predetermined proportion of an input packet has been received.
摘要翻译：在一个环的每个节点上都有接收（RX）和发送（TX）移位寄存器，与环串连在一起，用于传输一个公共长度的数据包环，接收时钟数据锁定到接收数据为接收寄存器（RX）提供时钟，以及为发送寄存器（TX）提供时钟的独立发送时钟。在接收寄存器（RX）中接收到分组中的同步位时，即在接收到预定比例的输入分组之后，发送时钟被触发。

摘要： A ring for circulating multiple packets each containing control information and data such as digitised audio, includes a monitor system for preventing the unwanted accumulation of "full" packets in the ring which have already circulated once and have consequently fulfilled their function. Each node normally cancels all packets it has originated, after one circulation of the ring. In case this system breaks down, a monitor node sets "on" a monitor flag in all the packets it receives and re-transmits and cancels any packets it receives which have failed to have been cancelled by the other nodes and in which the monitor flag is consequently still "on".
摘要翻译：用于循环多个包含控制信息和诸如数字化音频的数据的包的环包括用于防止环中已经已经循环一次并且因此实现其功能的“满”包不想要的累积的监视器系统。每个节点通常在环的一个循环之后取消它所产生的所有数据包。在该系统发生故障的情况下，监视节点在其接收的所有分组中设置“开启”监视器标志，并重新发送并取消其接收到的其他节点未被取消的任何数据包，其中监视器标志因此依然“开”。

摘要： An electronic token, preferably of the "smart card" type is affixed to an article and arranged for contactless coupling with a read/write unit.
In order to overcome the problem of security of paper documents, an electronic token of the type including on-board processing and memory is affixed to the document, and in use the document is placed so that the token couples with an external read/write terminal. Secure information may be accessed from or added to the token only by an authorised person having the correct passwords.
The token may also be provided on passports, cheque books, etc. It may further be provided on a vehicle and used to store licence and tax details, maintenance history and data relating to its owner or driver/operator.

摘要： The memory area within an electronic token of the 'smart card' type comprising a processor (4), memory (7, 8, 9) and input/output means (5) is divided into an execute only region and a non-volatile read/write region.
A method of loading an applications program is described in which the program is loaded into a portion of the read/write region by software methods and in which the application program may be altered if the use of the card alters.

摘要： Scanning imagers often comprise a plurality of detector elements which may be scanned in swathes to produce an image. To match the offsets or sensitivities of such elements the mean values of the channels adjacent each swathe boundary are compared, and an error signal produced which is fed back to equalise the values across each boundary. Proportionally smaller corrections are applied to the intermediate channels in each swathe. In this way the swathing or banding effect often associated with such imagers is much reduced.
摘要翻译：扫描成像器通常包括多个检测器元件，其可以被扫描以产生图像。为了匹配这些元件的偏移或灵敏度，比较与每个边界相邻的通道的平均值，并产生反馈信号以产生跨越每个边界的值的误差信号。比例较小的校正应用于每个槽中的中间通道。以这种方式，通常与这种成像器相关联的条纹或条纹效应大大降低。
