Abstract: A secure client authentication system may generate short-term x509 end-entity certificates and short-term private keys based on client-specific parameters and an expiration time. An x509 Certificate Authority (CA) may issue the short-term x509 certificates upon receiving a client request to access a secure endpoint. Each issued certificate may include a Time-To-Live (TTL) value that defines a limited validity period, facilitating ephemeral access to the secure endpoint. Automatic expiration of these access credentials may restrict to the secure endpoint beyond the limited validity period, enhancing security by mitigating risks associated with long-term static credentials.

Abstract: A perforating gun includes a gun assembly and a gun barrel. The gun assembly includes a charge tube comprising at least one shaped charge. A pin contact assembly is operably attached to a first end of the charge tube and includes a contact spacer and a through pin configured to provide electrical communication between respective perforating guns. An addressable switch assembly is attached to a second end of the charge tube and comprises an addressable switch and a detonator. The gun assembly is situated within the gun barrel and is configured to self-orient inside the gun barrel.

Abstract: A perforating gun includes a charge tube, a switch carrier body, and a pin contact spacer. The switch carrier body houses an addressable switch, a spring tube which holds a spring, a detonation block, a removable interrupter, and a pin contact spacer supporting a pin contact assembly. The spring biases a switch contact terminal towards an outer surface of the switch carrier body, and the switch contact terminal is electrically connected to the addressable switch. The interrupter includes first and second portions, and is temporarily adhered to the switch carrier body such that the first portion covers the switch contact terminal and the second portion extends between a detonation cord and an instantaneous detonator in the detonation block. A first end of the charge tube is positioned around the switch carrier body, and a second end of the charge tube is secured to the pin contact space.

Abstract: A wireline release head system includes a housing, a cutter box situated within the housing, a fire control switch, and a wireline extending through the cutter box and in electrical communication with a control unit and the fire control switch. The cutter box includes a piston assembly operable to move within a first track and a cutter knife operable to move within a second track. The second track is angled relative to the first track. The fire control switch is in communication with a fire detonator, which is selectively activatable to detonate a power charge. An electrical signal selectively sent through the wireline from the control unit to the fire control switch detonates the power charge, which causes the piston assembly to move within the first track and contact the cutter knife causing the cutter knife to move within the second track, thereby severing the wireline.

Abstract: A 3-dimensional (3D) video receiver may be operable to convert a decompressed 3D video frame having a 3D video interlaced format to generate a first 3D video frame having a first 3D video progressive format by performing an inverse pulldown. The generated first 3D video frame having the first 3D video progressive format may be converted to generate a second 3D video frame having a second 3D video progressive format. The generated first 3D video frame having the first 3D video progressive format may be scaled to generate the second 3D video frame having the second 3D video progressive format. When the 3D video receiver is operating in an electronic program guide (EPG) mode or in a graphics over video mode, the generated second 3D video frame having the second 3D video progressive format may be blended with graphics.

Abstract: A 3-dimensional (3D) video receiver may be operable to scale a decompressed 3D video frame having a first 3D video progressive format to generate a 3D video frame having a second 3D video progressive format, where the second 3D video progressive format comprises a high-definition multimedia interface (HDMI) format. When operating in an electronic program guide mode or a graphics over video mode, the 3D video frame having the second 3D video progressive format may be blended with graphics. The 3D video frame having the second 3D video progressive format may be converted to generate a 3D video frame having a 3D video interlaced format by performing a pulldown. The 3D video frame having the second 3D video progressive format at a 50 Hz frame rate may be frame-rate upconverted to generate a 3D video frame having a third 3D video progressive format at a 60 Hz frame rate.

Abstract: In one embodiment, there is presented an integrated circuit. The integrated circuit comprises a transport processor and a host processor. The transport processor parses a media stream. The host processor determines whether a media stream is Blu-ray or HD-DVD and configures the transport processor based on whether the media stream is Blu-ray or HD-DVD.
