Abstract: A personal protective device is combined with a cellular telephone. Activation of either device causes activation of the other device. Activation is achieved by a switch or voice command. Upon activation, a message asking for assistance at the present location is sent to a previously agreed upon emergency contact. The smartphone also starts both audio and video recording, which are also part of the data sent to the emergency contact person or service. Additionally, the personal protective devices are integrated into a unit that may combine such items as a protective spray, Taser, strobe light, dye pack, siren and other deterrent technologies to ward off would-be attackers. These devices are integrated into a hand held unit that can be unobtrusively worn or carried in a purse or pocket or in the user's hand. An optical safety device is included to protect the user from a potential assailant approaching from rearward.

Abstract: Systems and methods that provide a facility for a dynamic media overlay. An end user provides data for the dynamic media overlay that is activated upon selection to permit end users to share information while receiving or sending video data. The overlay may be a hyperlink that can be selected to take an action indicated by information provided in the hyperlink. The hyperlink may be represented by audio or image information in the form of instructions or clickable “targets.” A content of information represented by the hyperlink can be dynamic so that selection of the hyperlink can result in different actions, depending upon the informational content. One or more flags may be provided to indicate that a new hyperlink or new informational content for a hyperlink is requested. The hyperlink may be provided in an overlay represented as a media layer, or may be embedded in the video media itself.

Abstract: One or more techniques and/or systems are provided for providing driver alerts. For example, a client device module (e.g., a smartphone, a vehicle navigation unit, etc.) may collect driving behavior information (e.g., braking patterns, vehicle speed, weather conditions, acceleration/deceleration patterns, etc.) and/or user specified information (e.g., a number of passengers) of a driver driving a vehicle. The client device module may provide the driving behavior information and/or the user specified information to a driver alert provider. The driver alert provider may maintain a driver profile for the driver based upon the driving behavior information and/or the user specified information. The driver alert provider may generate a driver alert (e.g., a driver risk score of the driver) based upon the driver profile, and may provide the driver alert to other drivers that are within a threshold distance of the vehicle.

The material-removing element includes an interior surface defining a generally conical-shaped cavity extending along the rotational axis and adapted to receive at least a longitudinal portion of a cone section of an expanded medical balloon for removing material from the longitudinal portion of the cone section to reduce a wall thickness of the cone section. Material may be removed continuously around a 360-degree exterior perimeter of the longitudinal portion of the cone section of the medical balloon to reduce the thickness of the balloon wall defining the cone section.
