The base station provides access to one or more networks and/or data communication to the handheld payment terminal when paired.

Abstract: Techniques to provide transaction redundancy in an IC include receiving an original memory access request directed to a first memory aperture, constructing a redundant memory access directed to a second memory aperture, and selectively returning a response of the first or second memory aperture to an originator based on contents of the responses. For a write operation, if acknowledgement indicators of the responses indicate success, a response is returned to the originator. For a read operation, if acknowledgement indicators of the responses indicate success and data returned in the response match one another, a response is returned to the originator. If the acknowledgement indicators indicate success, but the data does not match, a retry of the original and redundant read requests is initiated. If any of the acknowledgement indicators do not indicate success, an error is declared. In a mixed-criticality embodiment, the redundant memory access request may be constructed selectively.

Abstract: In an embodiment, a system attaches a patient reference array of a computer-assisted surgery system to a patient. The system includes a fixation post having a shaft having proximal and distal ends that are offset from. A threaded fastener is coupled to the shaft at the distal end that rotates relative to the shaft so as to engage internal threads of a pedicle screw, thereby causing the distal end of the shaft to translate in the anchor seat and urge the pedicle screw to transition from an unlocked configuration to a locked configuration. The attachment assembly has an arm that supports the patient reference array, and a coupler supported by the arm. The coupler has a fixation body that defines a recess that receives at least a portion of the fixation post, and an actuator that secures the attachment assembly to the fixation post.

Abstract: Systems and methods herein provide for improved email efficiency. Based on selections made while drafting an email, a user requesting a response can cause a calendar reminder to be generated and sent to a recipient for automatic entry on that recipient's electronic calendar. When the original sender indicates that an appropriate response has been received, the system can cause the calendar entry to be removed from the recipient's calendar. The system can also generate automatic reminder emails to prompt the recipient to respond to the sender. The sender can access a list of outstanding email responses that are still due from various recipients and modify the associated reminders as desired.

Abstract: Provided herein are systems and methods of manufacture and operation for a compact laser to achieve high-intensity output pulses. These compact laser resonators and methods rely upon separate and distinct functions of the laser resonator to be operated in balance such that the functions, while deleterious when separate are supportive of laser generation and growth when combined within a small volume laser resonator as described herein. The combined elements of the described laser resonator include a delicate balance that allows the laser to operate between plane-parallel operation and unstable operation. This operation mode further allows distinct methods of construction and operation that allow the compact laser to be reliably assembled and tested during assembly. Therefore, despite requiring a delicate balance of disparate elements, the described laser resonator results in a compact robust laser.

Abstract: Disclosed is a two-component curable polymeric system having increased viscosity. One component contains a homogeneous blend of a polyisocyanate and a homopolymer or copolymer of vinyl acetate. This component has a higher viscosity than the polyisocyanate alone, thereby increasing the viscosity of the two-component curable system. The other component of the two-component curable system is a composition containing an isocyanate reactive component. The polyisocyanate and the isocyanate reactive component react together (“cure”) to form a polymer. Typically, but not always, the isocyanate reactive component is a polyol or polyamine that is capable of reacting with the polyisocyanate, thereby forming a polyurethane (polyol) or polyurea (polyamine).

Abstract: Embodiments herein describe memories in a processor system in an integrated circuit (IC) that can be assigned to either a cache coherent domain or an I/O domain, rather than being statically assigned by a designer of the IC. That is, the user or customer can assign the memories to domain that best suits their desires. Further, the memories can be reassigned to a different domain if the user later changes her mind.
