Abstract: A control circuit for a first switch includes at least one transistor, the first switch being arranged in series with a second switch in an inverter arm of an electrical power supply device supplying a load connected to the mid-point of the series arrangement of the first and second switch. The control circuit is configured to adjust the gate-source voltage of the at least one transistor of the first switch according to a control scheme including, during a deactivation period of the first switch, the increase of the gate-source voltage in a time window including the deactivation of the second switch and the reduction of the gate-source voltage in a time window including the activation of the second switch.

Abstract: Methods and systems for preventing fraud in a remote workforce environment are disclosed, including an apparatus, comprising processor(s), system memory, non-transitory memory unit(s), and verification code; verifying if ECV is permitted to deliver a product and/or perform a service; if not, then notifying a supervisor; verifying if recipient of the product and/or service is correct; if not, then notifying the supervisor; and verifying if location and/or time of delivery of the product and/or performance of the service is correct; if not, then notifying the supervisor; and if determined that: the ECV is permitted to deliver the product and/or perform the service, the recipient of the product and/or service is correct, and the location and/or time of delivery of the product and/or performance of the service is correct, then notifying the ECV to proceed with the delivery of the product and/or performance of the service. Other embodiments are described and claimed.

Abstract: A hemodialysis apparatus includes: a dialysate-delivery system including at least one unit selected from the group consisting of (i) a dialysate-preparation unit, (ii) a dialysate-circulation unit, (iii) an ultrafiltrate-removal unit, and (iv) a dialysate-monitoring unit; and a user/machine interface operably connected to the dialysate-delivery system, the user/machine interface comprising a touch screen, the touch screen including a screen having (a) a target ultrafiltration display, (b) an ultrafiltration rate display, (c) a transmembrane pressure display, (d) an arterial pressure display, (e) a venous pressure display, (f) a dialysis fluid conductivity display, and (g) a dialysis fluid temperature display; and wherein at least one of the displays of the touch screen is selectable to adjust a setting displayed by the display, the setting used to operate at least one of (i) the dialysate-preparation unit, (ii) the dialysate-circulation unit, (iii) the ultrafiltrate-removal unit, and (iv) the dialysate-monito
