Design a field stand for our Control Panel & Battery Box. We field-deploy a portable equipment assembly at temporary pumping and water-monitoring sites (bypass pumping, lift stations, streambank pump setups, etc.). Each site needs a control cabinet, a battery box, and a cell/antenna mast set up quickly, then broken down and moved to the next site. We're looking for a new stand or frame to secure and hold this equipment in place at the site — this is NOT a carrying case or transport container for the equipment. The stand does still need to break down into portable pieces for transport between sites, and no single piece of it can weigh more than 50 lbs, but once assembled on site it needs to robustly and securely hold everything in place. Our current solution isn't working, and we want fresh design concepts from this challenge. Bonus points if your design incorporates wheels so it can be hand-trucked across terrain. The core pieces of equipment the stand needs to secure in place are: • A battery box — a Pelican 1630NF Protector Transport Case (see dimensions and reference photos below). It's heavy, so it currently doubles as ballast and sits low in the assembly to help anchor the center of gravity. • An LCU controller cabinet — a Saginaw Control & Engineering (SCE) SCE-2424PC polycarbonate enclosure (see dimensions and reference photos below). • A toolbox that houses a Starlink modem and electrical plugs. Incorporating this third box into the stand would be nice to have, but it's not required. Two masts also need to be incorporated into the design: the existing cell antenna mast, which carries 2–4 Wilson directional wideband antennas at the top and creates significant sail area (wind load) that the stand needs to resist, and a second mast/pole holder for a Starlink dish. We currently use cinder blocks for supplemental ballast weight, feel free to accommodate their use into the design, if needed. Equipment Dimensions: Battery Box — Pelican 1630NF Protector Transport Case Width 24.25 in, Depth 17.5 in, Length (height) 31.3 in Notes: Heavy — typically used low in the assembly as ballast / low center of gravity. Has an integrated telescoping handle and wheels on the case itself. Controller Cabinet — Saginaw SCE-2424PC Height 25.4 in, Width 26.68 in, Depth 11.41 in Notes: Polycarbonate enclosure; front-facing connectors/glands along one side (see drawing photo). Top and bottom of enclosure have a lip flange with bolt holes that can be used to secure a secondary frame (strut channel, etc) Toolbox — Starlink Modem / Electrical Plugs (nice-to-have) A third plastic box, roughly similar in scale to the battery box, housing a Starlink modem and electrical plugs. Exact dimensions can be provided if a designer wants to incorporate it — treat it as optional for concept purposes. Antenna Masts (two required) Cell antenna mast: vertical pole supporting 2–4 Wilson directional wideband antennas at the top. Exact pole diameter/height varies by site — designers should treat this as a mounting interface (e.g., a pipe clamp, mast collar, or bracket sized to a standard pipe OD) rather than a fixed dimension, and call out their assumed pole size in their submission. Starlink mast: a second, separate mast/pole holder to mount a standard or mini Starlink dish using the Starlink pole mount adapter. Same approach applies — treat as a mounting interface rather than a fixed dimension. Must-Have Requirements • One-person deployable: no single piece/component of the stand may weigh more than 50 lbs, and it must be liftable, positionable, and assembled on site by a single field technician without assistance. (Note: this is a stand that secures the equipment in place at the site — not a case or container that carries the equipment during transport.) • Must securely hold both: – The Pelican 1630NF battery box (24.25″ W x 17.5″ D x 31.3″ L) – The Saginaw SCE-2424PC controller cabinet (25.4″ H x 26.68″ W x 11.41″ D) • Must incorporate mounts/interfaces for two masts — the existing cell antenna mast (carrying 2–4 Wilson directional wideband antennas) and a second, separate mast/pole holder for a Starlink dish — and must remain stable under the combined wind (sail) load of both. • Both the controller cabinet and the battery box must be elevated a minimum of approximately 6 inches off the ground to protect against flooding/standing water — while still keeping the battery box mounted as low as practical on the frame to preserve a low center of gravity and overall stability. • Must be compatible with standard cinder blocks as supplemental ballast at the base (we already have these on hand and can continue using them if the design benefits from added weight/anchoring). • Must break down, fold, or disassemble easily for transport and storage — this is the main failure of our current stand. • Must include a way to organize excess cabling — e.g., S-hooks or similar points to hang coiled extension cord, pump cable, flowmeter cable, valve cable, and other site cabling — rather than leaving it loose on the ground. • Must hold up to outdoor field conditions: rain, mud, sun, and unimproved ground (grass, gravel, streambank, dirt pads). • Must look clean and professional at customer/field sites — this is a customer-facing appearance concern, not just function. Nice-to-Have Features • Tool-free or minimal-tool assembly and breakdown in the field. • Wheels, so the assembled stand can be moved into place with a hand truck/dolly. • Adjustable mast height or tilt-down mast for easier antenna installation/service at height. • Space or mounting to incorporate a third box — a toolbox housing a Starlink modem and electrical plugs — into the assembly (not required). • Compact folded/stored footprint for transport in a truck bed or trailer.

Self Balancing cane: Looking to develop a self balancing walking stick for old people. So whenever they stop or sit or do anything else they simply let go of the stick. the stick will balance it self and never fall down and it will stay upright. im open to new approaches and idea that gets what i want which is easy to use walking cane with self balancing ability and good looks

You will design a schematic diagram that shows a ship to ship loading using a conveyor belt. View this video on vimeo to get an idea of what I am trying to convey. http://vimeo.com/16217538 The video is of two ships, side by side with a spacer barge in the middle. The smaller ship is loading the larger ship with a conveyor belt. At 1.03 seconds into the video, you will see a drawing. That's the type of drawing I want. But mine will have measurements of both vessels, the spacer barge, conveyor belt length and angle. I will provide all measurements. See attached pdf for they type of drawings. The attached sample will give you an idea of the type of measurements I need on the drawing.
