An insole with heat generating system is disclosed, which comprises an insole, a piezoelectric module disposed inside the insole and electrically connected with each other to form an electrical circuit, two flexible conductive strips having a first conductive copper piece and a second conductive copper piece disposed thereon, and at least one resistive heating chip. Wherein the piezoelectric module generates the electrical energy through stepping on the insole, and then turns into the heat energy through the resistive heating chip, thereby generating a temperature for the insole, so the insole with heat generating system can adjust the temperature appropriately, its safety is high, most importantly, the invention does not need to add the battery to generate heat.

A system, recharge apparatus, and method includes transmit coils positioned in a pattern to allow at least one of the transmit coils to establish a wireless link with a receive coil positioned in proximity of the recharge apparatus. A power source is coupled to the transmit coils and configured to selectively energize ones of the transmit coils to transfer power to the receive coil. An energy efficiency detection circuit is configured to detect an electrical response of each one of the transmit coils when energized by the power source, the electrical response indicative of an energy efficiency between the one of the transmit coils and the receive coil. The power source selectively energizes ones of the transmit coils, selected according to a statistical analysis of an historical record and the electrical response indicative of the energy efficiency meeting a minimum efficiency criterion for energy transfer to the receive coil.

A massaging boot assembly for massaging a foot includes a boot that may be worn on a foot. A massage unit is coupled to the boot and the massage unit selectively massages the foot when the boot is worn. The massage unit is selectively turned on and off. A heating unit is coupled to the boot such that the heating unit is in thermal communication with the boot. The heating unit is selectively turned on to selectively heat the foot thereby enhancing therapeutic relief of the foot.

The footwear includes a sole, a plurality of massage units, and a controller. The sole provides a support to the underside of a user's foot when the user is wearing the footwear. The massage units each include a channel, a plunger, a spring, and an actuator. The plunger is disposed within the channel and may slide within it linearly. The plunger has a shaft which terminates in an applicator, the applicator being round and configured to provide pressure to the user's foot. The spring is configured to maintain the plunger within a contact-position when at rest. This contact-position occurs when the plunger is maximally distal to the spring. The actuator is able to draw the plunger against the spring and release the plunger in repetition when energized, enacting a massaging action. The controller is able to selectively engage the actuators.

A pneumatic energy conversion mechanism for use with footwear generates electricity from foot-strikes. The mechanism comprises: at least one air-chamber with an outlet disposed to be compressed on foot strikes and decompressed when the foot is lifted; a micro-electrical generator supported within a support air tube pneumatically connected with the at least one air-chamber's outlet, at its one end, while having its other end open; at least one unidirectional axial-flow micro-turbine, such as the wells turbine, having all its blades exposed to the airflow, thus providing a powerful torque the same micro-electrical generator.

The invention pertains to a detachable tongue (16) for a slipper, with the said tongue (16) incorporating: one upper part (20) designed to come into contact with a tibial area and an area located opposite the talus of the user's foot; one lower part (21) designed to come into contact with a rear part of the top of the user's foot; and a detachable connection system (17) that connects the said tongue (16) with the slipper (10); and a heating element (25) connected to the said lower part (21), such that the said heating element (25) can extend between a tip of the boot and the user's toes.

Linear movement of a heel strike sequence for a shoe insole can be converted into rotational movement. This rotational movement can cause rotation of an interior of a generator. Rotation of this interior of the generator can cause an electricity to be generated and outputted. The generator can be considered a source of damping, so at the start of the heel strike sequence the generator can be non-engaged. After some time, the generator can be engaged and in turn rotate. This can allow for standing inertia to be more quickly overcome.

A wearable heater and/or cooler device can include one or more fluid pumps, one or more conduits, and one or more chambers. The fluid pumps can be configured for generating flow of a fluid and comprise inlets and outlets. The conduits have first end portions and second end portions, and the first end portions of the conduits can be coupled to the outlets of the fluid pumps. The chambers can be coupled to second end portions of the conduits such that the fluid flows from the fluid pumps, through the conduits, and into the chambers. The chambers can be configured to enhance the desired thermal transport characteristics of the fluid for thermal transfer adjacent to a wearer's body.

Systems and methods are disclosed for recommending products or services by receiving a three-dimensional (3D) model of one or more products; performing motion tracking and understanding an environment with points or planes using accelerometer sensor and estimating light or color in the environment using one video camera without a depth sensor in a mobile phone; acquiring sensor data from sensors and optimizing features extracted from each image and sensor data, where a feature conveys data unique to the image at a specific pixel location; and projecting the product in the environment.

Temperature of the extremities is a significant factor in temperature control of the body due to the presence of thermal receptors in the extremities. The brain uses signals from these thermal receptors as an indication of environmental conditions, and responds accordingly. Thermal monitoring of extremities and adjustment of extremity temperature are valuable in controlling body temperature, leading to a more optimum body temperature in an array of environmental conditions. Devices, such as a wearable article, and an apparatus to monitor the temperature of extremities, adjust the temperature of the extremities in response to the monitored temperature.
