Abstract: An example cervical traction device is used in conjunction with a therapy table and is made up of: a traction assembly configured to cyclically apply a traction force to the cervical spine at an angle to the longitudinal axis of the cervical spine to bend the cervical spine; a frame configured to support the traction assembly, the frame includes an upright mast; and a curved orthosis adapted to rest directly on the therapy table and for being positioned under the cervical spine of a patient during treatment. The traction assembly includes a first pulley device connected to the upright mast of the frame, the first pulley device is adjustable along a length of the upright mast. The traction assembly is configured to bend the cervical spine about the curved orthosis while exerting the traction force.

Abstract: An example cervical traction device includes a traction assembly configured to cyclically apply a traction force to a patient's cervical spine at an angle to the longitudinal axis of the cervical spine to bend the cervical spine. The traction assembly is made up of an electric motor operably connected to a headgear by a traction line capable of transferring traction force generated by the electric motor to the headgear. The electric motor is operably connected to the traction line by a linkage and a linear actuator rod. Together, the linkage and the linear actuator rod are configured to convert torque generated by the electric motor into back-and-forth linear motion used to cyclically apply traction force to the traction line and thereby the headgear. The linear actuator rod is supported by two posts, each of the two posts includes an eyelet through which the linear actuator rod reciprocates.

Abstract: A passenger ticket, lodging, or other physical space availability may be monitored by obtaining an itinerary record or other dataset associated with a previous space allocation (a previously-booked itinerary or similar purchase, e.g.). This may include, for example, identifying a group of travel segments that corresponds to a ticket or other allocation, “fingerprinting” the allocation, and determining a schedule to periodically monitor terms associated with the allocation. During an availability-monitoring period, an up-to-date version of the itinerary record may be obtained and “fingerprinted,” for example, such fingerprints being usable to determine whether substitutions (identifying more preferable lodging or travel spaces, e.g.) have changed significantly or have already been discovered and implemented, and to take appropriate action (implementing a substitution or updating the itinerary record, e.g.) if so.

Abstract: A flight-ticket price may be monitored by obtaining an itinerary record associated with a previously-booked flight itinerary, identifying a group of flight segments that corresponds to a ticket, “fingerprinting” the ticket, and determining a schedule to periodically monitor prices associated with the ticket. During at least one price-monitoring period, an up-to-date version of the itinerary record is obtained and “fingerprinted”. The “fingerprints” are used to verify that the flight ticket has not changed significantly, current pricing data is obtained, and a cost saving is determined to be currently obtainable, considering possible change penalties, by re-ticketing or re-booking the group of flight segments.
