20090222065 | Physiological Parameter Analysis for an Implantable Restriction Device and a Data Logger - An implantable restriction device can be configured to provide a restriction in a patient, for example as a function of the pressure of fluid. The implantable restriction device can include one or more sensors configured to sense a variety of parameters, such as pressure of the fluid within the implantable restriction device, pulse width, pulse amplitude, pulse count, pulse duration, or frequency, electrical characteristics, or other parameters. Data obtained by the one or more sensors (for example, the data representing pressure, pulse characteristics, and so on) may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the data, and may communicate the data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger. The logged data may be analyzed and/or displayed using a variety of techniques to assess and/or track the condition of the restriction device or of the patient, to monitor patient physiology, or for other purposes. | 09-03-2009 |

20130152281 | CHIN PROTECTION SYSTEM - A chin protection system for releasable attachment to a wide variety of helmets through the use of an elastically-deformable helmet cover, a pliable retainer, and a chin protector. The system safely attaches to a helmet without any modifications to the helmet and therefore does not impact the warranty or safety rating of the helmet. The helmet cover is designed to stretch and conform to numerous different helmet styles and manufacturers, while serving as an attachment point for the pliable retainer. The pliable retainer provides the tensile force necessary to keep the chin protector in place throughout the range of movement common during sporting activities, as well as during an impact to the chin. The chin protection system may be utilized on any safety helmet including, but not limited to, bike helmets, skateboard helmets, rollerblade helmets, ski/snowboard helmets, motorcycle helmets, go-cart helmets, baseball and softball helmets, and climbing helmets. | 06-20-2013 |
