Abstract: An example portable apparatus for logging propulsion data associated with a manual mobility assistance device is described herein. The portable apparatus can include an accelerometer configured to detect acceleration of the manual mobility assistance device, an angular position sensor configured to detect rotation of a wheel of the manual mobility assistance device, and a controller operably coupled to the accelerometer and the angular position sensor. The controller can include a processor and a memory operably coupled to the processor, the memory having computer executable instructions stored thereon, that when executed by the processor, cause the processor to receive acceleration data detected by the accelerometer and angular position data detected by the angular position sensor, and store the acceleration data and the angular position data in the memory. The accelerometer, the angular position sensor, and the controller can be configured to removably couple to the manual mobility assistance device.

Abstract: A carrier for items such as fast food includes a box-like base and a handle. A bottom opening in the base may be used to hold a drink cup which is then placed within a cup holder in the user's vehicle to anchor the carrier. When the user lifts the drink cup tabs remain inside the cup holder anchoring the carrier to the cup holder. The carrier can be anchored to cup holders of varying sizes.
