Abstract:
Some embodiments are directed to a computing device comprising a volatile memory comprising multiple rows of memory cells, each row of the multiple rows of memory cells having a neighboring row, and a memory mapper configured to map a first plurality of the multiple rows to a safe memory region, and a second plurality of the multiple rows to an unsafe memory region, wherein a row of the first plurality does not have a neighboring row in the first plurality.
Abstract:
The present disclosure relates to an apparatus (100) and method for controlling a plurality of simultaneously active optical traps (OT1, OT2, OT3). In one method, trapping beams (TB1, TB2, TB3) are provided and redirected for individually controlling a respective position (X,Y) of optical traps (OT1, OT2, OT3) formed by focusing of the redirected trapping beams in a sample volume (SV). Light (L11,L20) from the sample volume (SV) corresponding to the optical traps is received. A path of a detector beam (AB) is overlapped with one of the trapping beams (TB3), wherein the detector beam has a distinct wavelength (λA) from that of the overlapping trapping beam (TB3). In one channel, the light from the sample volume is filtered according to wavelength, and only the filtered light having the wavelength (λA) of the detector beam (AB) is measured.
Abstract:
A method for managing communication in a wireless mesh network comprising a plurality of wireless nodes and a wireless node for use in such network are described, wherein said method may comprise: providing a time slot schedule (frame), preferably a TDMA time slot schedule (frame), comprising one or more time slots, including a transmission time slot enabling a node to transmit a broadcast message, a reception time slot enabling a node to receive a broadcast message from one or more other nodes; and/or a sleep time slot for configuring said node in an idle state; and, assigning said time slots to nodes in said network on the basis of the position of said nodes in said network.
Abstract:
A suture device includes a needle operating device movable longitudinally with respect to a housing between at least an insertion position and a needle transfer position. The needle operating device includes an elongate operating element arranged extending from a distal end of the housing to or near a housing proximal end. A needle holder connected at a distal end of the operating element holds two or more needles, with free ends directed in proximal direction. The holder is movable with respect to a protection device between at least a protecting position shielding the free ends, and a non-protecting position for the same. A needle receive device at a distal end of the housing receives the free ends when the operating device is moved to the transfer position. In at least the insertion position the holder and the protection device are spaced longitudinally from the housing to receive a tissue therebetween.
Abstract:
The invention relates to a system for predicting the viability of a body tissue in a patient. The system comprises a computing device, and a first pressure measuring device for measuring local perfusion pressure in the body tissue of the patient. This measuring device is connected to the computing device. A second pressure measuring device is provided for measuring the systemic perfusion pressure of the patient, said second pressure measuring device being connected to the computing device. A feedback indicator is connected to the computing device and is adapted to indicate the viability of the tissue calculated by the computing device on the basis of the measured local and systemic perfusion pressures. The invention also includes a method of predicting the viability of the body tissue and to the first pressure measuring device.
Abstract:
A system (100) for interrogating a photonic circuit (10). A sample light source (30s) is configured to generate sample input light (Li) at a sample frequency (vs). An input coupler (21) is configured to send the sample input light (Li) from the sample light source (30s) into the photonic circuit (10). An output coupler (22) is configured to receive sample output light (Lo) from the photonic circuit (10). A reference light source (30r) is configured to generate reference light (Lr) at a reference frequency (vr). An optical heterodyne detector (40) is configured to combine the sample output light (Lo) with the reference light (Lr); measure the combined light (Lc); and determine a magnitude (P) of an oscillating intensity component (I) in the combined light (Lc) as function of a beating frequency (f) between the sample frequency (vs) and the reference frequency (vr).
Abstract:
