Automobile central lock and ABS hardware in loop simulation testing system was developed based on MATLAB/Simulink and dSPACE, dSPACE’s standard component MicroAutoBox is the central control node, used to receive speed signal, key position signal skid ratio and remote signal, together with dealing with these signals. Sending relative signals to CAN SJA1000 and CAN PCA82C250 which SCM use STC89C52RC, each node actuates relative motion to control automobile’s door lock and ABS system. ABS executer implements relative brake based of these signals requirements. The result indicates that dSPACE simulation platform can quickly build up model and control system.

A scheme of improving performance of hydrostatic journal support was presented, that is, control journal support pose by controlling flow of four controllable chambers and Coupling various oil film thickness, to assure journal support expected pose; Chamber flow can be regulated by electro hydraulic servo valve-control variable pump according to the surface roughness, load, cutting force, and thermal results of journal support. The mathematical model of the controllable chambers flow, servo variable mechanism and controller were built; the pose control model was established, which contain the kinematics positive and negative solution and control strategy of hydraulic cylinder position feedback; Hardware-in-loop simulation experiment was carried on the electro hydraulic servo test bench by mean of the non-linear relation of film thickness and the hydraulic cylinder displacement. Simulation and Hardware-in-loop simulation experiment results show that the controllable journal support exhibit high oil film rigidity can stably and quickly track the expected goal and can be broadly applied in high precision heavy horizontal machine tool.

Abstract Family caregivers (FCs) of institutionalized noncommunicative older persons reported multiple unmet communication needs focusing on the need to receive reliable and regular updates on the patient’s condition. We have developed a mobile app for improving communication between FCs and healthcare professionals (HPs), based on 152 interviews with FCs and 13 discussion groups with HPs from four Israeli geriatric facilities. Both parties participated in app planning, tailoring it to their needs and abilities. App use implementation encountered major obstacles including the bureaucratic process concerning signing contracts between the university and software development firms, which hindered the process for a full year; data security department required disproportionate security levels that interfered with user experience and delayed the development process; the study’s definition varied across different ethics/Helsinki committees (Institutional Review Boards; IRBs), which led to different demands, e.g., insurance for medical clinical trials although no drugs or medical device were involved; lack of cooperation by mid-level staff members despite the institutional adoption of the app project; low utilization by HPs resulted in FCs not receiving timely responses. Despite these and other obstacles, we tested app use for 15 months in one facility in a pre-post-design with intervention and control groups, and we have since begun testing it in another facility. FCs who had used the app had positive feedback and wished to continue using it. App use optimization requires implementation planning, assimilating changes in each facility’s work procedures and HP’s engagement and motivation and thus depends on institutional procedures and politics.
