Abstract: A robotic meal preparation system includes a robotic meal assembly device configured to assemble a meal using multiple ingredients; a computer-implemented system is configured to display to a consumer a menu or list of meal choices, in which a specific meal has a number of different main ingredients, each at a pre-set weight, and the system is further configured to enable the consumer to select a meal and to then vary or set the weight of one or more of the main ingredients of that selected meal, to form a customised or personalised version of that selected meal. The robotic meal assembly device is then configured to assemble that customised or personalised version of that meal. The system hence provides complete meal personalisation, with high levels of consistency, greatly increasing customer satisfaction and reducing food waste. And does so quickly and efficiently, based on rapid, robotic preparation of each meal.

Abstract: Broadly speaking, embodiments of the present techniques provide a configurable robotic processing system in which the sequence of operations performed by the system may vary (in contrast to a conveyor-based system) and may be dynamically-scheduled.

Abstract: A data processing system 2 is provided which is responsive to program instructions that operate in a variable timing mode to require a variable number of processing cycles to complete. The system is also operable in a fixed timing mode, which may be programmable using a bit (or several bits) within a configuration controlling register, to operate in a fixed timing mode in which such instructions are forced to operate using a fixed number of processing cycles. Thus, suppression of instructions which fail their condition codes may be suppressed and early termination of program instructions similarly suppressed in a manner which helps resist an attack upon the security of the system by observing the number of processing cycles required to process certain data.

Abstract: There is provided an apparatus for processing data, said apparatus comprising: a processor operable in a plurality of modes and either a secure domain or a non-secure domain including: at least one secure mode being a mode in said secure domain; and at least one non-secure mode being a mode in said non-secure domain; wherein when said processor is executing a program in a secure mode said program has access to secure data which is not accessible when said processor is operating in a non-secure mode; and a vectored interrupt controller operable to generate an exception handler address for supply to said processor in response to occurrence of an exception condition in accordance with programmable parameters specifying: for each of a plurality of exception conditions, a domain value indicating whether said exception condition should trigger an exception handler in said secure domain or said non-secure domain; for each of said plurality of exception conditions, an exception handler address for use if said excepti

Abstract: A data processing apparatus and method are provided for controlling access to a slave device, the slave device having an address range associated therewith. The apparatus comprises control storage programmable to define a partition identifying a secure region and a non-secure region in the address range, with the data processing apparatus supporting a plurality of modes of operation including a secure mode, and the control storage being programmable only by software executing in the secure mode. A master device is arranged to issue an access request onto a bus, the access request identifying a sequence of addresses within the address range and including a control signal indicating whether the access request is a secure access request or a non-secure access request. The secure region is only accessible by a secure access request.

Abstract: A method and apparatus estimate the detection range R.sub.1 of a radar in the presence of noise and clutter. The radar return signals from a range cell under test and from a plurality of surrounding range cells on either side of the range cell under test are measured. From the values of the return signals from the surrounding cells, a factor .alpha. is determined. The mean value of those signals is then multiplied to form a threshold value for determining the presence or absence of a target. A desired false alarm rate is maintained, however. A number of radar return signals sufficient substantially to average out local variations in clutter are used to determine a mean clutter value m.sub.c. A value which is a function of .alpha. and m.sub.c is output as the estimate of detection range R.sub.1.

Abstract: A circuit for generating an output signal L indicative of the mean clutter level at a selected location in the field of view of a radar apparatus, particularly the sea surface which exhibits a swell pattern. The circuit includes processing circuits which generate weighting coefficients (a.sub.1, a.sub.2, . . . a.sub.N) used to weight the amplitudes of returns derived respectively from a group of N discrete locations which precede in range and or succeed in range the selected location. The circuit generates the elements r(n) of a matrix [r] which represents the auto correlation function of the amplitude of returns derived from w discrete locations encompassing the group of N locations. Circuit then uses the matrix [r] to compute the weighting coefficients (a.sub.1, a.sub.2. . . a.sub.N) which are stored at 13 applied to respective multiplying circuits to weight corresponding amplitudes accessed to respective locations of a shift register.

Abstract: There is disclosed a synthetic aperture radar arranged to survey a region from a mobile location. The radar returns received from the region are first phase weighted by a series of predetermined factors. They are then stored and combined with later returns to give an output signal which has a maximum value when any target present in the region is in a predetermined direction from the location.
