A test device for rigid-flexible characteristics of a rigid-flexible transition overhead conductor rail, includes a movable vehicle moved in a length extending direction of the overhead conductor rail. A telescopic mechanism for providing lifting force for the overhead conductor rail is mounted on the movable vehicle and stretches out and draws back in a vertical direction, and a conversion plate is connected to a top end of the telescopic mechanism and synchronously moved in the vertical direction therewith. A sliding assembly is mounted at a top of the conversion plate and slides along the overhead conductor rail with the movable vehicle. The overhead conductor rail is located over the sliding assembly which abuts against a bottom wall of the overhead conductor rail. A force sensor is arranged between the telescopic mechanism and the conversion plate. A displacement detection mechanism is arranged on the conversion plate.

A switching converter includes a power circuit, a control circuit, and a regulation circuit. The power circuit regulates an output current through the load with at least one main switching transistor. The control circuit couples to the power circuit and controls on and off states of the at least one main switching transistor in accordance with a reference voltage received to control a minimum peak inductor current through an inductor. The regulation circuit provides the reference voltage to the control circuit and adaptively regulates the reference voltage in accordance with the input voltage and the output voltage. An effect of a duty ratio on an inductor current can be canceled out when the duty cycle changes due to fluctuations in the input and output voltages. An output current is kept approximately constant in a burst mode, thereby effectively reducing output ripple and noise.

Protection of process memory against foreign code injection is described herein. A system includes at least one processor and at least one memory storing instructions thereon that, when executed by the at least one processor, cause the at least one processor to perform operations. The operations include to dynamically virtualize a protected application in user space, wherein the virtualization comprises a virtualized memory management system and to monitor memory allocated to the virtualized protected application by the virtualized memory management system. The operations include to compare memory allocated by the virtualized memory management system with known allocations of virtual memory. Additionally, the applications include to designate the memory as being injected with foreign code in response to the virtualized memory management system detecting privileges not created by the virtualized memory management system.

Protection of process memory against foreign code injection

Systems and methods for obfuscating keyboard keys against interception are provided. In an example, a protected application is dynamically virtualized in user space, wherein the virtualization comprises an isolated keyboard path. Keystrokes are injected to the isolated keyboard path, wherein the injected keystrokes are associated with a respective timestamp, and user input keystrokes are obfuscated with the injected keystrokes and the obfuscated keystrokes are passed to a low level hook. The obfuscated keystrokes passed to the low level hook are separated according to tags associated with the obfuscated keystrokes to obtain the user input keystrokes. The user input keystrokes are transmitted to a target window of the protected application.

Method to obfuscate keyboard keys against interception

In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.
