System with integrated haptic feedback for canine communication

A system for providing haptic feedback independent of leash tension, comprising:

• a housing configured to attach to an operator-side portion of a leash and including a leash-engaging structure;
• a level detector configured to sense an angle of the housing relative to gravity;
• a control unit operatively coupled to the level detector;
• and
• a haptic engine operatively coupled to the control unit and configured to generate a series of periodic signals that are conveyed through the leash to a recipient,
• wherein the control unit actuates the haptic engine to emit the periodic signals when the sensed angle exceeds a threshold and thereby provides non-correctional, angle-based feedback independent of leash tension.

A system for providing haptic feedback for communication with a recipient, comprising:

• a feedback mechanism configured to generate a series of periodic signals, the signals being perceptible to the recipient as a non-correctional indicator;
• a transmission interface configured to convey the signals through a leash, collar, or other wearable device to the recipient;
• and
• a control mechanism configured to adjust one or more parameters of the signals,
• wherein the system dynamically adapts to variations in calculated distance without requiring manual adjustments and does not interfere with corrective training signals.

A system for estimating a separation between an operator and a tethered recipient, comprising:

• a leash or tether configured to physically couple the recipient to at least one of the operator and a fixed object;
• a housing configured to be attached to the leash or tether at a location between the operator or fixed object and the recipient;
• a level sensor disposed in the housing and configured to sense an orientation of the housing relative to gravity;
• a memory storing a leash-length parameter indicative of a distance between the housing and at least one of the operator and an anchor point;
• and
• a processor operatively coupled to the level sensor and the memory and configured to determine an angle of the leash or tether relative to gravity based on the sensed orientation, compute an estimated separation between the operator or anchor point and the recipient as a function of the angle and the leash-length parameter, and generate a distance signal indicative of the estimated separation for use by one or more applications associated with at least one of the operator and the recipient.
