Abstract: An apparatus has processing circuitry and a memory system. The memory system is responsive to a first type of memory access operation for which a time taken to handle the memory access operation is unbounded, the operation is able to change contents of data stored in the memory system, and a response is required. The apparatus has memory access operation handling circuitry that receives an indication of an interrupt to be taken while a memory access operation of the first type is being handled by the memory system and determines whether the memory access operation has reached a stage for which a remaining time to complete the memory access operation will be bounded. In dependence on the remaining time, the memory access operation handling circuitry either stalls the interrupt until the memory access operation has completed or aborts the memory access operation and allow the interrupt to be taken.

Abstract: There is provided an apparatus that includes a first port that receives first data of a first type from a first storage circuit. A second port receives second data of a second type from a second storage circuit having a lower worst case latency in hardware than the first storage circuit. A third port receives access requests for the first data and the second data from a processing circuit. When one of the access requests is received for the first data, it is forwarded to the first storage circuit and when the one of the access requests is received for the second data, it is forwarded to the second storage circuit. A shared storage circuit stores the first data and the second data and has a storage capacity.

Abstract: The present concept is a patio heater assembly. The patio heater assembly includes a base and at least one support platform spaced from the base that is supported and attached to a vertically extending rear upright and at least one vertically extending forward upright. The uprights are attached at one end to the base and the other end to the at least one support platform. There is a pole moveable between a collapsed position and a raised assembled position that includes at least one pole flange at a bottom end of the pole. The pole flange rigidly connects to the support platform when in the raised assembled position, thereby maintaining the patio heater assembly in the raised assembled position. While in the collapsed position the pole flange rests on the base.

Abstract: A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots are controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.

Abstract: An optical fiber communication system is described that includes a data source that generates electrical data. A transmission filter filters the electrical data generated by the data source and passes a transmission spectrum. The transmitter filter has a transfer function that reduces adjacent symbol interference in a transmission spectrum. The bandwidth of the transmitter filter may be substantially optimized bandwidth. A modulator modulates the transmission spectrum on an optical signal. The modulator may be a substantially chirp-free modulator. A detector detects the modulated optical signal transmitted across an optical channel and converts the detected modulated optical signal to a received electrical data signal. A receiver filter filters the received electrical data signal. The receiver filter has a transfer function that reduces adjacent symbol interference in the received electrical data signal.

Modification component (130) modifies the phase component of the error signal (110) in response to the envelope component of the input signal to reduce variation of a phase component of the power amplifier output signal (194).
