The assembly can also include a manual actuator extending from the control hub and configured to allow the steerable shaft to be manually steered by a user's hand, and a robotic actuator housed by and/or extending from the control hub configured to connect to a robotic driver to allow robotic steering of the steerable shaft.

Abstract: Techniques for automatically securing receptacles of a retailer via an electronic lock include receiving a user request to reserve a receptacle, selecting a suitable receptacle based on one or more conditions, some of which may be specified by the user, and transmitting an electronic locking signal to secure, and thereby reserve, the selected receptacle. An association between the reserved receptacle and the user is stored, and the user is electronically notified. Subsequently, an electronic signal indicative of the identification of the user (or of the user's agent) is locally received. Upon determination that the user is expected and associated with the reserved receptacle, the techniques include causing an electronic unlocking signal to be transmitted to the electronic lock, thereby unlocking the receptacle.

Abstract: Systems, methods, and techniques for mitigating retail theft include securing items at a receptacle of a retailer via an electronic lock, and providing a transceiver that is proximate to the secured items and that transmits a beacon which may be detected by a personal electronic device (PED) of a customer. Based on a wireless transmission between the PED and the transceiver, a customer's identity may be determined and the customer's risk profile may be accessed. A risk score corresponding to the customer accessing the secured item may be determined based on the customer's risk profile and optionally based upon a profile of the secured item. If the risk score is indicative of an acceptable risk, a trigger to remotely unlock the electronic lock may be sent, thereby remotely and automatically allowing qualified customers to access secured items. An item's removal may be detected and tracked.

Abstract: Magnetic resonance imaging (MRI) systems and methods using adiabatic tip-down and matched adiabatic flip-back pulses are disclosed. According to an aspect, a system includes a signal generator configured to generate a pulse sequence for on-resonance magnetization transfer preparation. The pulse sequence includes an adiabatic tip-down pulse and a matched adiabatic flip-back pulse for separating spins in a mobile spin pool from spins in a bound spin pool of an anatomical region of interest for imaging. The system includes radio frequency (RF) coils configured to transmit RF pulses in response to the pulse sequence and to acquire RF data in response to transmission of the RF pulses. Further, the system includes a processing system configured to process the RF data to provide a display image indicating different tissue types with discrimination.

Abstract: A computer input device configured to accept a user's hand palm down is disclosed. A handle is affixed on top of a stick, which in turn is secured to a base, where the user moves the handle with the user's palm to move the stick relative to the base in a plurality of axes. The handle includes a plurality of buttons that can be activated by the user's digits. The computer input device has a low overall profile with a low center of gravity and a relatively small footprint and is preferably used in conjunction either with another computer input device of a similar configuration or a computer mouse-style input device.

Abstract: Methods and systems for obtaining intravascular magnetic resonance images of blood flow are disclosed. In preferred forms, a train of radio frequency (RF) pulses is produced by an intravascularly introduced RF transmitter positioned in proximate location to the blood flow so as to create a continuous stream of coherently excited protons of the blood flow. The coherently excited protons of the blood flow are sampled as the protons freely precess while flowing through a region of three dimensional space unaffected by the ongoing intravascular RF excitation. An image of the sampled coherently excited protons may then be constructed.
