Patent CA-2897747-A1 (CA)
Title: Memory introspection engine for integrity protection of virtual machines
Inventor: LUTAS ANDREI-VLAD
IPC: G06F9/455
Filed: 2014-02-04
Abstract: Described systems and methods allow protecting a computer system from malware, such as viruses and rootkits. In some embodiments, a hypervisor configures a hardware virtualization platform hosting a set of operating systems (OS). A memory introspection engine executing at the processor privilege level of the hypervisor dynamically identifies each OS, and uses an protection priming module to change the way memory is allocated to a target software object by the memory allocation function native to the respective OS. In some embodiments, the change affects only target objects requiring malware protection, and comprises enforcing that memory pages containing data of the target object are reserved exclusively for the respective object. The memory introspection engine then write-protects the respective memory pages.

Patent CA-2899840-A1 (CA)
Inventor: VOICULESCU DAN AMARIEI
IPC: F15B15/26
Filed: 2014-01-15
Abstract: A locking mechanism for locking an actuator piston within an actuator cylinder housing is disclosed. The locking mechanism comprises a locking pin that is moveable between extended and retracted positions. The locking pin can be moved using a controller, such as a hydraulic controller, for example. In the extended position the locking pin engages the actuator piston thereby locking the actuator piston in a specific position. The locking mechanism includes a mechanical bias (such as a spring or other mechanical system) that biases the locking pin towards an extended position to lock the actuator piston when counter-pressure on the locking pin is lower than the pressure provided by the mechanical bias. The locking pin can be hydraulically operated so that hydraulic pressure that forces the actuator piston to retract also exerts force on the locking pin to move it from a locked position to an unlocked position.
Patent CA-2900673-A1 (CA)
Inventor: PANSKY AMIR
IPC: F16H21/20
Filed: 2014-01-30
Abstract: Device and method for enabling independent tuning of frequency and amplitude of a reverse crankshaft motor. The reverse crankshaft motor provides periodic reciprocating motion based on periodic rotational motion from a rotational motor. The reverse crankshaft motor includes a crankshaft structure having first and second frames with a third axle arranged between them and connected to them by hinges. An amplituder is affixed to the third axle and may communicate with an external device. As the first and second frames move toward or apart from each other, the third axle moves radially toward or away from a central axis of the crankshaft structure. The position of the third axle determines the amplitude of the periodic reciprocating motion of the amplituder. By adjusting the position of the first and second frames, the operator may adjust the amplitude independently from the frequency of the periodic rotational motion supplied by the rotational motor.
